Deckard’s Photo Inspector

Back to Blade Runner. I mean, the pandemic is still pandemicking, but maybe this will be a nice distraction while you shelter in place. Because you’re smart, sheltering in place as much as you can, and not injecting disinfectants. And, like so many other technologies in this film, this will take a while to deconstruct, critique, and reimagine.


Doing his detective work, Deckard retrieves a set of snapshots from Leon’s hotel room, and he brings them home. Something in the one pictured above catches his eye, and he wants to investigate it in greater detail. He takes the photograph and inserts it in a black device he keeps in his living room.

Note: I’ll try and describe this interaction in text, but it is much easier to conceptualize after viewing it. Owing to copyright restrictions, I cannot upload this length of video with the original audio, so I have added pre-rendered closed captions to it, below. All dialogue in the clip is Deckard.

Deckard does digital forensics, looking for a lead.

He inserts the snapshot into a horizontal slit and turns the machine on. A thin, horizontal orange line glows on the left side of the front panel. A series of seemingly random-length orange lines begin to chase one another in a single-row space that stretches across the remainder of the panel and continue to do so throughout Deckard’s use of it. (Imagine a news ticker, running backwards, where the “headlines” are glowing amber lines.) This seems useless and an absolutely pointless distraction for Deckard, putting high-contrast motion in his peripheral vision, which fights for attention with the actual, interesting content down below.

If this is distracting you from reading, YOU SEE MY POINT.

After a second, the screen reveals a blue grid, behind which the scan of the snapshot appears. He stares at the image in the grid for a moment, and speaks a set of instructions, “Enhance 224 to 176.”

In response, three data points appear overlaying the image at the bottom of the screen. Each has a two-letter label and a four-digit number, e.g. “ZM 0000 NS 0000 EW 0000.” The NS and EW—presumably North-South and East-West coordinates, respectively—immediately update to read, “ZM 0000 NS 0197 EW 0334.” After updating the numbers, the screen displays a crosshairs, which target a single rectangle in the grid.

A new rectangle then zooms in from the edges to match the targeted rectangle, as the ZM number—presumably zoom, or magnification—increases. When the animated rectangle reaches the targeted rectangle, its outline blinks yellow a few times. Then the contents of the rectangle are enlarged to fill the screen, in a series of steps which are punctuated with sounds similar to a mechanical camera aperture. The enlargement is perfectly resolved. The overlay disappears until the next set of spoken commands. The system response between Deckard’s issuing the command and the device’s showing the final enlarged image is about 11 seconds.

Deckard studies the new image for awhile before issuing another command. This time he says, “Enhance.” The image enlarges in similar clacking steps until he tells it, “Stop.”

Other instructions he is heard to give include “move in, pull out, track right, center in, pull back, center, and pan right.” Some include discrete instructions, such as, “Track 45 right” while others are relative commands that the system obeys until told to stop, such as “Go right.”

Using such commands he isolates part of the image that reveals an important clue, and he speaks the instruction, “Give me a hard copy right there.” The machine prints the image, which Deckard uses to help find the replicant pictured.

This image helps lead him to Zhora.

I’d like to point out one bit of sophistication before the critique. Deckard can issue a command with or without a parameter, and the inspector knows what to do. For example, “Track 45 right” and “Track right.” Without the parameter, it will just do the thing repeatedly until told to stop. That helps Deckard issue the same basic command when he knows exactly where he wants to look and when doesn’t know what exactly what he’s looking for. That’s a nice feature of the language design.

But still, asking him to provide step-by-step instructions in this clunky way feels like some high-tech Big Trak. (I tried to find a reference that was as old as the film.) And that’s not all…

Some critiques, as it is

  • Can I go back and mention that amber distracto-light? Because it’s distracting. And pointless. I’m not mad. I’m just disappointed.
  • It sure would be nice if any of the numbers on screen made sense, and had any bearing with the numbers Deckard speaks, at any time during the interaction. For instance, the initial zoom (I checked in Photoshop) is around 304%, which is neither the 224 or 176 that Deckard speaks.
  • It might be that each square has a number, and he simply has to name the two squares at the extents of the zoom he wants, letting the machine find the extents, but where is the labeling? Did he have to memorize an address for each pixel? How does that work at arbitrary levels of zoom?
  • And if he’s memorized it, why show the overlay at all?
  • Why the seizure-inducing flashing in the transition sequences? Sure, I get that lots of technologies have unfortunate effects when constrained by mechanics, but this is digital.
  • Why is the printed picture so unlike the still image where he asks for a hard copy?
  • Gaze at the reflection in Ford’s hazel, hazel eyes, and it’s clear he’s playing Missile Command, rather than paying attention to this interface at all. (OK, that’s the filmmaker’s issue, not a part of the interface, but still, come on.)
The photo inspector: My interface is up HERE, Rick.

How might it be improved for 1982?

So if 1982 Ridley Scott was telling me in post that we couldn’t reshoot Harrison Ford, and we had to make it just work with what we had, here’s what I’d do…

Squash the grid so the cells match the 4:3 ratio of the NTSC screen. Overlay the address of each cell, while highlighting column and row identifiers at the edges. Have the first cell’s outline illuminate as he speaks it, and have the outline expand to encompass the second named cell. Then zoom, removing the cell labels during the transition. When at anything other than full view, display a map across four cells that shows the zoom visually in the context of the whole.

Rendered in glorious 4:3 NTSC dimensions.

With this interface, the structure of the existing conversation makes more sense. When Deckard said, “Enhance 203 to 608” the thing would zoom in on the mirror, and the small map would confirm.

The numbers wouldn’t match up, but it’s pretty obvious from the final cut that Scott didn’t care about that (or, more charitably, ran out of time). Anyway I would be doing this under protest, because I would argue this interaction needs to be fixed in the script.

How might it be improved for 2020?

What’s really nifty about this technology is that it’s not just a photograph. Look close in the scene, and Deckard isn’t just doing CSI Enhance! commands (or, to be less mocking, AI upscaling). He’s using the photo inspector to look around corners and at objects that are reconstructed from the smallest reflections. So we can think of the interaction like he’s controlling a drone through a 3D still life, looking for a lead to help him further the case.

With that in mind, let’s talk about the display.


To redesign it, we have to decide at a foundational level how we think this works, because it will color what the display looks like. Is this all data that’s captured from some crazy 3D camera and available in the image? Or is it being inferred from details in the 2 dimensional image? Let’s call the first the 3D capture, and the second the 3D inference.

If we decide this is a 3-D capture, then all the data that he observes through the machine has the same degree of confidence. If, however, we decide this is a 3D inferrer, Deckard needs to treat the inferred data with more skepticism than the data the camera directly captured. The 3-D inferrer is the harder problem, and raises some issues that we must deal with in modern AI, so let’s just say that’s the way this speculative technology works.

The first thing the display should do it make it clear what is observed and what is inferred. How you do this is partly a matter of visual design and style, but partly a matter of diegetic logic. The first pass would be to render everything in the camera frustum photo-realistically, and then render everything outside of that in a way that signals its confidence level. The comp below illustrates one way this might be done.

Modification of a pair of images found on Evermotion
  • In the comp, Deckard has turned the “drone” from the “actual photo,” seen off to the right, toward the inferred space on the left. The monochrome color treatment provides that first high-confidence signal.
  • In the scene, the primary inference would come from reading the reflections in the disco ball overhead lamp, maybe augmented with plans for the apartment that could be found online, or maybe purchase receipts for appliances, etc. Everything it can reconstruct from the reflection and high-confidence sources has solid black lines, a second-level signal.
  • The smaller knickknacks that are out of the reflection of the disco ball, and implied from other, less reflective surfaces, are rendered without the black lines and blurred. This provides a signal that the algorithm has a very low confidence in its inference.

This is just one (not very visually interesting) way to handle it, but should illustrate that, to be believable, the photo inspector shouldn’t have a single rendering style outside the frustum. It would need something akin to these levels to help Deckard instantly recognize how much he should trust what he’s seeing.

Flat screen or volumetric projection?

Modern CGI loves big volumetric projections. (e.g. it was the central novum of last year’s Fritz winner, Spider-Man: Far From Home.) And it would be a wonderful juxtaposition to see Deckard in a holodeck-like recreation of Leon’s apartment, with all the visual treatments described above.


Also seriously who wants a lamp embedded in a headrest?

…that would kind of spoil the mood of the scene. This isn’t just about Deckard’s finding a clue, we also see a little about who he is and what his life is like. We see the smoky apartment. We see the drab couch. We see the stack of old detective machines. We see the neon lights and annoying advertising lights swinging back and forth across his windows. Immersing him in a big volumetric projection would lose all this atmospheric stuff, and so I’d recommend keeping it either a small contained VP, like we saw in Minority Report, or just keep it a small flat screen.

OK, so we have an idea about how the display would (and shouldn’t) look, let’s move on to talk about the inputs.


To talk about inputs, then, we have to return to a favorite topic of mine, and that is the level of agency we want for the interaction. In short, we need to decide how much work the machine is doing. Is the machine just a manual tool that Deckard has to manipulate to get it to do anything? Or does it actively assist him? Or, lastly, can it even do the job while his attention is on something else—that is, can it act as an agent on his behalf? Sophisticated tools can be a blend of these modes, but for now, let’s look at them individually.

Manual Tool

This is how the photo inspector works in Blade Runner. It can do things, but Deckard has to tell it exactly what to do. But we can still improve it in this mode.

We could give him well-mapped physical controls, like a remote control for this conceptual drone. Flight controls wind up being a recurring topic on this blog (and even came up already in the Blade Runner reviews with the Spinners) so I could go on about how best to do that, but I think that a handheld controller would ruin the feel of this scene, like Deckard was sitting down to play a video game rather than do off-hours detective work.

(I hope we can pay this loan back.)

Similarly, we could talk about a gestural interface, using some of the synecdochic techniques we’ve seen before in Ghost in the Shell. But again, this would spoil the feel of the scene, having him look more like John Anderton in front of a tiny-TV version of Minority Report’s famous crime scrubber.

One of the things that gives this scene its emotional texture is that Deckard is drinking a glass of whiskey while doing his detective homework. It shows how low he feels. Throwing one back is clearly part of his evening routine, so much a habit that he does it despite being preoccupied about Leon’s case. How can we keep him on the couch, with his hand on the lead crystal whiskey glass, and still investigating the photo? Can he use it to investigate the photo?

Here I recommend a bit of ad-hoc tangible user interface. I first backworlded this for The Star Wars Holiday Special, but I think it could work here, too. Imagine that the photo inspector has a high-resolution camera on it, and the interface allows Deckard to declare any object that he wants as a control object. After the declaration, the camera tracks the object against a surface, using the changes to that object to control the virtual camera.

In the scene, Deckard can declare the whiskey glass as his control object, and the arm of his couch as the control surface. Of course the virtual space he’s in is bigger than the couch arm, but it could work like a mouse and a mousepad. He can just pick it up and set it back down again to extend motion.

This scheme takes into account all movement except vertical lift and drop. This could be a gesture or a spoken command (see below).

Going with this interaction model means Deckard can use the whiskey glass, allowing the scene to keep its texture and feel. He can still drink and get his detective on.

Tipping the virtual drone to the right.

Assistant Tool

Indirect manipulation is helpful for when Deckard doesn’t know what he’s looking for. He can look around, and get close to things to inspect them. But when he knows what he’s looking for, he shouldn’t have to go find it. He should be able to just ask for it, and have the photo inspector show it to him. This requires that we presume some AI. And even though Blade Runner clearly includes General AI, let’s presume that that kind of AI has to be housed in a human-like replicant, and can’t be squeezed into this device. Instead, let’s just extend the capabilities of Narrow AI.

Some of this will be navigational and specific, “Zoom to that mirror in the background,” for instance, or, “Reset the orientation.” Some will more abstract and content-specific, e.g. “Head to the kitchen” or “Get close to that red thing.” If it had gaze detection, he could even indicate a location by looking at it. “Get close to that red thing there,” for example, while looking at the red thing. Given the 3D inferrer nature of this speculative device, he might also want to trace the provenance of an inference, as in, “How do we know this chair is here?” This implies natural language generation as well as understanding.

There’s nothing from stopping him using the same general commands heard in the movie, but I doubt anyone would want to use those when they have commands like this and the object-on-hand controller available.

Ideally Deckard would have some general search capabilities as well, to ask questions and test ideas. “Where were these things purchased?” or subsequently, “Is there video footage from the stores where he purchased them?” or even, “What does that look like to you?” (The correct answer would be, “Well that looks like the mirror from the Arnolfini portrait, Ridley…I mean…Rick*”) It can do pattern recognition and provide as much extra information as it has access to, just like Google Lens or IBM Watson image recognition does.

*Left: The convex mirror in Leon’s 21st century apartment.
Right: The convex mirror in Arnolfini’s 15th century apartment

Finally, he should be able to ask after simple facts to see if the inspector knows or can find it. For example, “How many people are in the scene?”

All of this still requires that Deckard initiate the action, and we can augment it further with a little agentive thinking.

Agentive Tool

To think in terms of agents is to ask, “What can the system do for the user, but not requiring the user’s attention?” (I wrote a book about it if you want to know more.) Here, the AI should be working alongside Deckard. Not just building the inferences and cataloguing observations, but doing anomaly detection on the whole scene as it goes. Some of it is going to be pointless, like “Be aware the butter knife is from IKEA, while the rest of the flatware is Christofle Lagerfeld. Something’s not right, here.” But some of it Deckard will find useful. It would probably be up to Deckard to review summaries and decide which were worth further investigation.

It should also be able to help him with his goals. For example, the police had Zhora’s picture on file. (And her portrait even rotates in the dossier we see at the beginning, so it knows what she looks like in 3D for very sophisticated pattern matching.) The moment the agent—while it was reverse ray tracing the scene and reconstructing the inferred space—detects any faces, it should run the face through a most wanted list, and specifically Deckard’s case files. It shouldn’t wait for him to find it. That again poses some challenges to the script. How do we keep Deckard the hero when the tech can and should have found Zhora seconds after being shown the image? It’s a new challenge for writers, but it’s becoming increasingly important for believability.

Though I’ve never figured out why she has a snake tattoo here (and it seems really important to the plot) but then when Deckard finally meets her, it has disappeared.


  • Interior. Deckard’s apartment. Night.
  • Deckard grabs a bottle of whiskey, a glass, and the photo from Leon’s apartment. He sits on his couch and places the photo on the coffee table.

  • The machine on top of a cluttered end table comes to life.
  • Deckard
  • Let’s look at this.
  • He points to the photo. A thin line of light sweeps across the image. The scanned image appears on the screen, pulled in a bit from the edges. A label reads, “Extending scene,” and we see wireframe representations of the apartment outside the frame begin to take shape. A small list of anomalies begins to appear to the left. Deckard pours a few fingers of whiskey into the glass. He takes a drink before putting the glass on the arm of his couch. Small projected graphics appear on the arm facing the inspector.
  • Deckard
  • OK. Anyone hiding? Moving?
  • Photo inspector
  • No and no.
  • Deckard
  • Zoom to that arm and pin to the face.
  • He turns the glass on the couch arm counterclockwise, and the “drone” revolves around to show Leon’s face, with the shadowy parts rendered in blue.
  • Deckard

  • Deckard rolls his eyes.
  • Deckard
  • Zoom to the face and pin.
  • The view zooms to the face, but the camera is level with her chin, making it hard to make out the face. Deckard tips the glass forward and the camera rises up to focus on a blue, wireframed face.
  • Deckard
  • That look like Zhora to you?
  • The inspector overlays her police file.
  • Photo inspector

  • Why didn’t you say so?
  • Photo inspector
  • My threshold is set to 66%.
  • Deckard
  • Give me a hard copy right there.
  • He raises his glass and finishes his drink.

This scene keeps the texture and tone of the original, and camps on the limitations of Narrow AI to let Deckard be the hero. And doesn’t have him programming a virtual Big Trak.

Deckard’s Elevator

This is one of those interactions that happens over a few seconds in the movie, but turns out to be quite deep—and broken—on inspection.

When Deckard enters his building’s dark, padded elevator, a flat voice announces, “Voice print identification. Your floor number, please.” He presses a dark panel, which lights up in response. He presses the 9 and 7 keys on a keypad there as he says, “Deckard. 97.” The voice immediately responds, “97. Thank you.” As the elevator moves, the interface confirms the direction of travel with gentle rising tones that correspond to the floor numbers (mod 10), which are shown rising up a 7-segment LED display. We see a green projection of the floor numbers cross Deckard’s face for a bit until, exhausted, he leans against the wall and out of the projection. When he gets to his floor, the door opens and the panel goes dark.

A need for speed

An aside: To make 97 floors in 20 seconds you have to be traveling at an average of around 47 miles per hour. That’s not unheard of today. Mashable says in a 2014 article about the world’s fastest elevators that the Hitachi elevators in Guangzhou CTF Finance Building reach up to 45 miles per hour. But including acceleration and deceleration adds to the total time, so it takes the Hitachi elevators around 43 seconds to go from the ground floor to their 95th floor. If 97 is Deckard’s floor, it’s got to be accelerating and decelerating incredibly quickly. His body doesn’t appear to be suffering those kinds of Gs, so unless they have managed to upend Newton’s basic laws of motion, something in this scene is not right. As usual, I digress.

The input control is OK

The panel design is nice and was surprising in 1982, because few people had ridden in elevators serving nearly a hundred floors. And while most in-elevator panels have a single button per floor, it would have been an overwhelming UI to present the rider of this Blade Runner complex with 100 floor buttons plus the usual open door, close door, emergency alert buttons, etc. A panel that allows combinatorial inputs reduces the number of elements that must be displayed and processed by the user, even if it slows things down, introduces cognitive overhead, and adds the need for error-handling. Such systems need a “commit” control that allows them to review, edit, and confirm the sequence, to distinguish, say, “97” from “9” and “7.” Not such an issue from the 1st floor, but a frustration from 10–96. It’s not clear those controls are part of this input.

Deckard enters 8675309, just to see what will happen.

I’m a fan of destination dispatch elevator systems that increase efficiency (with caveats) by asking riders to indicate their floor outside the elevator and letting the algorithm organize passengers into efficient groups, but that only works for banks of elevators. I get the sense Deckard’s building is a little too low-rent for such luxuries. There is just one in his building, and in-elevator controls work fine for those situations, even if they slow things down a bit.

The feedback is OK

The feedback of the floors is kind of nice in that the 7-segment numbers rise up helping to convey the direction of movement. There is also a subtle, repeating, rising series of tones that accompany the display. Most modern elevators rely on the numeracy of its passengers and their sense of equilibrium to convey this information, but sure, this is another way to do it. Also, it would be nice if the voice system would, for the visually impaired, say the floor number when the door opens.

Though the projection is dumb

I’m not sure why the little green projection of the floor numbers runs across Deckard’s face. Is it just a filmmaker’s conceit, like the genetic code that gets projected across the velociraptors head in Jurassic Park?

Pictured: Sleepy Deckard. Dumb projection.

Or is it meant to be read as diegetic, that is, that there is a projector in the elevator, spraying the floor numbers across the faces of its riders? True to the New Criticism stance of this blog, I try very hard to presume that everything is diegetic, but I just can’t make that make sense. There would be much better ways to increase the visibility of the floor numbers, and I can’t come up with any other convincing reason why this would exist.

If this was diegetic, the scene would have ended with a shredded projector.

But really, it falls apart on the interaction details

Lastly, this interaction. First, let’s give it credit where credit is due. The elevator speaks clearly and understands Deckard perfectly. No surprise, since it only needs to understand a very limited number of utterances. It’s also nice that it’s polite without being too cheery about it. People in LA circa 2019 may have had a bad day and not have time for that shit.

Where’s the wake word?

But where’s the wake word? This is a phrase like “OK elevator” or “Hey lift” that signals to the natural language system that the user is talking to the elevator and not themselves, or another person in the elevator, or even on the phone. General AI exists in the Blade Runner world, and that might allow an elevator to use contextual cues to suss this out, but there are zero clues in the film that this elevator is sentient.

There are of course other possible, implicit “wake words.” A motion detector, proximity sensor, or even weight sensor could infer that a human is present, and start the elevator listening. But with any of these implicit “wake words,” you’d still need feedback for the user to know when it was listening. And some way to help them regain attention if they got the first interaction wrong, and there would be zero affordances for this. So really, making an explicit wake word is the right way to go.

It might be that touching the number panel is the attention signal. Touch it, and the elevator listens for a few seconds. That fits in with the events in the scene, anyway. The problem with that is the redundancy. (See below.) So if the solution was pressing a button, it should just be a “talk” button rather than a numeric keypad.

It may be that the elevator is always listening, which is a little dark and would stifle any conversation in the elevator less everyone end up stuck in the basement, but this seems very error prone and unlikely.

Deckard: *Yawns* Elevator: Confirmed. Silent alarm triggered.

This issue is similar to the one discussed in Make It So Chapter 5, “Gestural Interfaces” where I discussed how a user tells a computer they are communicating to it with gestures, and when they aren’t. 

Where are the paralinguistics?

Humans provide lots of signals to one another, outside of the meaning of what is actually being said. These communication signals are called paralinguistics, and one of those that commonly appears in modern voice assistants is feedback that the system is listening. In the Google Assistant, for example, the dots let you know when it’s listening to silence and when it’s hearing your voice, providing implicit confirmation to the user that the system can hear them. (Parsing the words, understanding the meaning, and understanding the intent are separate, subsequent issues.)

Fixing this in Blade Runner could be as simple as turning on a red LED when the elevator is listening, and varying the brightness with Deckard’s volume. Maybe add chimes to indicate the starting-to-listen and no-longer-listening moments. This elevator doesn’t have anything like that, and it ought to.

Why the redundancy?

Next, why would Deckard need to push buttons to indicate “97” even while he’s saying the same number as part of the voice print? Sure, it could be that the voice print system was added later and Deckard pushes the numbers out of habit. But that bit of backworlding doesn’t buy us much.

It might be a need for redundant, confirming input. This is useful when the feedback is obscure or the stakes are high, but this is a low-stakes situation. If he enters the wrong floor, he just has to enter the correct floor. It would also be easy to imagine the elevator would understand a correction mid-ride like “Oh wait. Elevator, I need some ice. Let’s go to 93 instead.” So this is not an interaction that needs redundancy.

It’s very nice to have the discrete input as accessibility for people who cannot speak, or who have an accent that is unrecognizable to the system, or as a graceful degradation in case the speech recognition fails, but Deckard doesn’t fit any of this. He would just enter and speak his floor.

Why the personally identifiable information?

If we were designing a system and we needed, for security, a voice print, we should protect the privacy of the rider by not requiring personally identifiable information. It’s easy to imagine the spoken name being abused by stalkers and identity thieves riding the elevator with him. (And let’s not forget there is a stalker on the elevator with him in this very scene.)

This young woman, for example, would abuse the shit out of such information.

Better would be some generic phrase that stresses the parts of speech that a voiceprint system would find most effective in distinguishing people.

Tucker Saxon has written an article for VoiceIt called “Voiceprint Phrases.” In it he notes that a good voiceprint phrase needs some minimum number of non-repeating phonemes. In their case, it’s ten. A surname and a number is rarely going to provide that. “Deckard. 97,” happens to have exactly 10, but if he lived on the 2nd floor, it wouldn’t. Plus, it has that personally identifiable information, so is a non-starter.

What would be a better voiceprint phrase for this scene? Some of Saxon’s examples in the article include, “Never forget tomorrow is a new day” and “Today is a nice day to go for a walk.” While the system doesn’t care about the meaning of the phrase, the humans using it would be primed by the content, and so it would just add to the dystopia of the scene if Deckard had to utter one of these sunshine-and-rainbows phrases in an elevator that was probably an uncleaned murder scene. but I think we can do it one better.

(Hey Tucker, I would love use VoiceIt’s tools to craft a confirmed voiceprint phrase, but the signup requires that I permit your company to market to me via phone and email even though I’m just a hobbyist user, so…hard no.)

Deckard: Hi, I’m Deckard. My bank card PIN code is 3297. The combination lock to my car spells “myothercarisaspinner” and my computer password is “unicorn.” 97 please.

Here is an alternate interaction that would have solved a lot of these problems.

  • Voice print identification, please.
  • Have you considered life in the offworld colonies?
  • Confirmed. Floor?
  • 97

Which is just a punch to the gut considering Deckard is stuck here and he knows he’s stuck, and it’s salt on the wound to have to repeat fucking advertising just to get home for a drink.

So…not great

In total, this scene zooms by and the audience knows how to read it, and for that, it’s fine. (And really, it’s just a setup for the moment that happens right after the elevator door opens. No spoilers.) But on close inspection, from the perspective of modern interaction design, it needs a lot of work.

R. S. Revenge Comms

Note: In honor of the season, Rogue One opening this week, and the reviews of Battlestar Galactica: The Mini-Series behind us, I’m reopening the Star Wars Holiday Special reviews, starting with the show-within-a-show, The Faithful Wookie. Refresh yourself of the plot if it’s been a while.


On board the R.S. Revenge, the purple-skinned communications officer announces he’s picked up something. (Genders are a goofy thing to ascribe to alien physiology, but the voice actor speaks in a masculine register, so I’m going with it.)


He attends a monitor, below which are several dials and controls in a panel. On the right of the monitor screen there are five physical controls.

  • A stay-state toggle switch
  • A stay-state rocker switch
  • Three dials

The lower two dials have rings under them on the panel that accentuate their color.

Map View

The screen is a dark purple overhead map of the impossibly dense asteroid field in which the Revenge sits. A light purple grid divides the space into 48 squares. This screen has text all over it, but written in a constructed orthography unmentioned in the Wookieepedia. In the upper center and upper right are unchanging labels. Some triangular label sits in the lower-left. In the lower right corner, text appears and disappears too fast for (human) reading. The middle right side of the screen is labeled in large characters, but they also change too rapidly to make much sense of it.

The ship’s ramp and doors


External door & ramp

The door to the ship is a vertical slit in the otherwise seamless fuselage. The ramp extends and retracts as part of the door’s function. Gort is the only one in control of it. Klaatu can instruct Gort to open it with the command “Beringa!” and Gort wirelessly initiates the opening sequence.

This might seem to be a questionable security feature, since if Gort is not around, Klaatu cannot enter into the sanctuary of his ship. Fortunately Gort is both indestructible and immovable. The only time he leaves the proximity of the ship is after Klaatu dies. So it seems like his is like an invincible, semi-intelligent, and loyal concierge.


Internal doors

The internal doors are operated by proximity, but only open for Gort and Klaatu. They remain shut even as Helen pounds against them. This implies a combination of proximity sensor and some form of authentication. Since the ship does not display any of the intelligence that Gort does, this authentication is more likely to be something like an RFID chip than biometric authentication.
