I have to admit that the only reason I got turned on to Metropolis was because of the "Radio GaGa" video, and for the longest time the only version I knew of the film was the Giorgio Moroder hack job back in the 80's.

Have you seen Dr Mabuse? It is perhaps his second best film, although the run time can be difficult for some people at 270 minutes. Brilliant film though, I saw it at a retrospective at a local repertory theatre several years ago, and then just recently it was up on MUBI.
