I've never seen "Goodbye Lenin," but have read good reviews about it. There is one more foreign film that just barely made it within the 25 year time limit:
Repentance (1984) by Tengiz Abuladze. It is one of the most extraordinarily moving films I have ever seen. It chronicles the "terror" in Stalinist Russia from the viewpoint of a Georgian village. It actually came out during the late "Glaznost" period before the Wall came down. It's the closest thing we have to a film version of
The Gulag Archipelago. Probably the closest we'll get in a long time, too.
Repentence is one of the most moving films I have ever seen.
Ugh, bad link. Here's a correct one:
Repentance
I find the reviews at the Amazon site express my opinions to a 't.'
