Ugetsu monogatari
Ran/Rashomon/Dreams (can't decide)
A.I. - Artificial Intelligence

Der Himmel über Berlin
Some are the original titles, because I don't know the English translation or either because I've only watched them in the original version with subtitles. In general, they're written in no particular order.
Sad to notice that the greatest part of people here completely ignore the existance of foreign, old and/or non-mainstream movies...
