Fitz Langs legendary masterpiece Metropolis has been rediscovered. The film was heavily edited for American audiences, with key scenes being cut out. For 80 years the edited version has been all that is available. Now we can see it in its former glory.
According to the article, what has been found is the complete original film before any edits have been made. The copy has to be cleaned up and restored, but otherwise, it doesn’t have to be integrated with anything else, as it contains all scenes currently known and those previously unknown.
Ran into the edit window.
It is like the Star Trek pilot episode The Cage. It was cut up to make up the episode The Menagerie, and the complete color episode was subsequently thought to be lost. Then a complete copy of it was found in a film lab in the 1980’s.
I know that historically Metropolis is far more important than The Cage, but the circumstances are similar.
