2017 marks 90 years since Fritz Lang premiered Metropolis.

Now considered a science-fiction classic that’s influenced subsequent generations of sci-fi film makers.

In 1984, Giorgio Moroder released a restored, colorized version with music soundtrack performed by Moroder, Freddie Mercury, Pat Benatar, Bonnie Tyler, Billy Squier, and others.  The release included as much of the original film that could be found and restored.  The original, complete 1927 version is yet to be discovered.
