A few weeks ago I sat down to watch Fritz Lang’s most famous film, Metropolis (1927) and during the opening credits the titlecards commented on missing reels.
It seems the original 200+ minute version of the film, unseen since the premiere in 1927, surfaced in Argentina. The link is to a website that published the article in 2008, but I found it in Empire Magazine, stating a DVD release of the original version in 2010.

It’s U.S. premiere is going to be at TCM’s classic movie festival in Hollywood in April…so the DVD will probably be out sometime after that. Pretty cool, even if it makes a long film even longer!
Thanks for the follow up Merritt. Could you send me your source so I can post this (with you to credit of course)?
