OK, Luth, "Hair" gets onto my list. I happen to know that the world premiere of the musical was exactly 41 years ago.
Last good movie I watched was a German one named "Einer bleibt sitzen" ("One remains seated"). It's about a young man who suffers from paraplegia after a road accident which he doesn't remember. He had that accident because he found out that his girlfriend left him for his best friend, but due to his amnesia he forgot that. Still he's about to give himself up completely. His best friend, feeling guilty, moves him to participate in a rehabilitation camp - but to do so this friend promised to join the camp incognito and to spend that time in the wheelchair himself. It's a very emotional and touching movie about hope, friendship, guilt, despair, and it's very well done, seeming very authentic. A big recommendation!
Cheers!
