I did some photography for the San Francisco Film Museum last week and I got a chance to see Metropolis with the recently added footage. The Alloy Orchestra provided the score live.
It's long, but it was so amazing. I highly recommend taking some time to see it.
The photos are here: http://sanfranciscofilmmuseum.org/
Note that I got to photograph the people that found and restored the footage and Leonard Maltin. That was awesome. (I didn't post-process the photos, though.)
That's pretty cool, Dottie!
very cool, you got to restore some history!
