this, it's easy to overlook that the film is also just another love story.
In Metropolis the future is now - our now. We are living Lang's vision of the future. The faces of those coal miners trapped 245 feet underground as they emerged from the rescue baskets are reminders that miners and other laborers are still working deep underground and that there are people everywhere in the world working like automatons to keep our prosperity afloat.
Set in the twenty-first century, Metropolis tells a familiar tale of a corporate upper class that lives in towering angular skyscrapers, cavorting amid fountains, gardens, and peacocks, with airplanes, cars, and trains to shuttle them about. Lang's city supposedly was inspired by his first glimpse of the New York skyline from the deck of a ship. Far below this realm of skyscrapers and luxury lies the misery and drudgery of catwalks, furnaces, factories, and a mechanical devotion to machinery.
Mr. Frederson owns all of these foundries and factories. During a frivolous romp through his gardens and fountains, Frederson's son, Freder, spots Maria, the daughter of one of the workers. She is playing with a group of children, and he's smitten with her fresh-faced innocence. Sneaking a peek at the condition of the workers in the underground, Freder is shocked by the multitude of faceless bodies and the dark, airless atmosphere.
