The issue with Metropolis is which of the many versions does one synch Pink Floyd to?
I’m surprised nobody has fanedited the Moroder version, (my introduction to the film in the 80’s, and still a favorite) adding in recovered lost footage and extending the songs.
is this the version you speak of ?..https://www.hollywoodreporter.com/heat-vision/rock-version-silent-film-classic-227317 if so , would love to get my hands on it .I first became aware of this film in art school when one of my teachers brought in a vhs tape for us to watch in an art history class . I love this film in any version .
