Worker 11811, where are you?

Saw the German silent movie Metropolis this weekend at the Belcourt. It was good. I'd try to explain the plot here, but you'd never believe it. When the slave laborers were being herded up the steps and into the machine in the early part of the movie, I couldn't help but think it was an eerie foreshadowing of what would happen in that country just a dozen years later, with masses of innocent people led to their deaths in work camps.
