I just found out about this story from a co-worker. I am so pumped about this.
Lost scenes from Metropolis found – Boing Boing
The original version of Fritz Lang’s fantastic science fiction film Metropolis was first seen in Berlin in 1927. Shortly after, Paramount recut the film to (over)simplify the plot. From then on, it was thought that at least 1/4 of the whole film ended up on the editing room floor where it was swept into the dustbin of history. Recently though, much of the lost footage was rediscovered.
