Restored (again?)
From the Metropolis Wikipedia Page:
On July 1, 2008, Berlin film experts announced that a 16mm reduction negative of the original cut of the film, which runs over 210 minutes in length, had been discovered in the archives of the film museum Museo del Cine in Buenos Aires, Argentina. The find has been authenticated by film experts working for ZEITmagazin. The print is badly scratched and will require considerable restoration before it is viewable. British Broadcasting Corporation's teletext service reported on July 4-5, 2008 that the only copy of the film had now received its first viewing.
Apparently the film will be released by Kino. I had a look at their page for it, and the description reads (in part):
Now, restored in Germany with state-of-the-art digital technology, under the supervision of the Murnau Foundation, and with the original 1927 orchestral score by Gottfried Huppertz added, Metropolis can be appreciated in its full glory. It is, as A. O. Scott of The New York Times declared, "A fever dream of the future. At last we have the movie every would-be cinematic visionary has been trying to make since 1927." (my emphasis)
This may be referring to their 2001 restoration though, and new footage may have to be inserted still. Having seen at least two previous "restored" versions (and yes, I liked Moroder's version except it's score) I'll wait and see.
The version I have on my shelf was bought for $2 at Go-Lo, and there's no telling which version it is.
