Metropolis is one of the greatest films ever made. It's amazing set design, brilliant cinematography, groundbreaking special effects and futuristic story truly makes it one of the must-sees in cinema!
It is set in the future, in a city called Metropolis where the citizens are divided into two groups: workers (who live under the ground and are working 10 hour shifts by enormous machines that keeps Metropolis working) and the royals (living in luxury in the great city on the surfice). And over them all, is the creator of Metropolis: Joh Fredersen (Alfred Abel). His son Freder (Gustav Fröhlich) falls in love with a woman of the working-class called Maria (Brigitte Helm) who preaches that a mediator will come and create peace and equality for both workers and royals. Joh Fredersen sees Maria as a big threat agains his "order", so he and the inventor Rotwang (Rudolf Klein-Rogge) kidnaps her and copies her appearence onto a robot, which will destroy the workers faith in Maria. However, Rotwang secretly plans to programme the robot to make the workers destroy the city and crush Joh Fredersen, as an act of vengeance against Fredersen for a sin he committed in the past...
Lang made this film in 1927, and it was a huge blockbuster event of that year. However, after the premiere, the US distributor heavily cut down the film, and thereafter the original version was considered lost for almost a decade. In 2008 they found the original version in Argentina (very damaged, but watchable), which became the basis for the most recent reconstruction (2010). If you are going to watch this movie (as I highly recommend that you do!) that's the version to watch!
Overall, Metropolis is a REALLY REALLY great movie, that you, once again, MUST watch!
I give it a 10/10
