Joh is the civil and capital leader of Metropolis, and his large office reflects it in the amount of technology it has. To the left of the door is Josaphat’s work interface (see Middle Class Oppression for more detail). To the right are two other pieces of technology: a large video screen hangs high, and a video phone rests on the wall below.
Joh Frederson paces in his office.
His desk also features some impressive technology. He has a bell jar ticker machine for receiving information. A large output panel on the right side of his desk allows people to request his attention. It features a huge array of thin bulbs labeled with particular codes. In one scene, Joh hears a sound and lifts his head to see a blinking light next to one of the labels. In response he touches a button on a control panel on the left of his desk to close the curtains, and then another to open the door to his office and receive Josephat.
Joh notices that Josephat wishes to speak to him.
Joh closes the curtains from his desk.
Later he uses another button on this same panel to summon his agent, called the Thin Man.
Joh closes the curtains from his desk.
These interfaces are particular to Joh, conveniences only available to one in a position of wealth and power.
Laborers of the Upper City have their own machines to worry about.
Josaphat feels stress while monitoring figures.
One of Johs assistants, Josaphat, has a similarly difficult task. He stands at a tall panel where lit symbols fall quickly and randomly down one of six tall, thin screens. He has to transcribe them (and possibly perform calculations with them) in one of three different books.
Josaphat turns his station off.
The only sensible part of this setup is the mechanism for shutting it down. Given the time pressure its operator is under, it could be disastrous if a single switch was accidentally touched. Instead, to turn it off Josephat must stretch his arms to reach two distant buttons. Touching them both shuts down the station. This seems especially prescient when considering that similar constraints informed the design of the familiar CTRL-ALT-DELETE key sequence for Windows operating systems.
Laborers in the Lower City live lives of horrible dehumanization, tending to and dying in the maw of the machines. Much of the technology in the early part of the film highlights this aspect of the world of Metropolis.
One shift files in as the other files out.
Access to and from the machine halls are carefully controlled. Between shift changes, laborers line up in regimented rows before the gates. A device on the wall adjacent to the gate shines two square lights up top. When that light extinguishes and the circular light illuminates, the laborers know to begin walking through the gates.
They trudge to large elevators, where an operator turns a crank wheel to raise the containing gate and lower the elevator. This elevator operator keeps his eyes on a gauge positioned uncomfortably high on the wall above the crank.
Freder encounters the worker’s city.
A laborer fails to monitor the temperature of the M-machine.
One exhausted laborer has to control the temperature of the machine. He stands before a panel where a thermometer is mounted in the dead center. Its markings tell him the acceptable maximum temperature. A row of flanges and levers line the lower part of the wall. Each has a lightbulb above it. When the lightbulb illuminates, the laborer must activate that flange. The pattern of blinking lights is difficult to keep up with and the work exhausting.
11811 struggles to keep up with his task at the machine.
When Feder returns to the Lower City, he sees a laborer tending a particularly pointless machine. He holds two arms on a human-sized, clock-like face. Instead of numbers, the face is ringed by lightbulbs. Every half a second, the two blinking bulbs will dim, and a new completely random pair will begin blinking. The laborer’s task is to turn the hands such that each one points to the blinking lights. 11811 struggles to keep up with his task at the machine.
Feeling for his brother, Freder offers to take 11811’s place at the machine.
Though too fast and random to be easily sustainable, the task itself is so apparent that Feder can offer to stand in after only a few seconds of watching.
