Ooh - good thread idea!
Well, I LOVE the credits from Delicatessen - that's just sheer brilliance.
And of course, you have to love the James Bond series - they've set the standards for action films.
Some of my favorites -
Wings of Desire
Much Ado About Nothing
Both of these because of the use of dialogue, with nothing but the printed word on the big screen, and a single voice intoning those words.
Apacolypse, Now
Because it starts with The Doors' "This is the End," and it really is, beginning with the final sequences of the film, and these surreal explosions of Napalm at night.
The Wedding Singer - shuddup!
It's cute, with a wedding scene that cracks me up every time.
Jesus Christ, Superstar
The bus scene, which it ends with, as well, but withou the actor who plays Jesus. Plus, they do all their warmups, and a dance sequence. Fade to Judas on the hilltop - again, brilliant, and very well choreographed.
Oh, so many films, so little space to write! I'll have to come back with more...
