In the Mood for Love should be high on the list for any self respecting film geek. It's a good way to ease into the Wong Kar-Wai's other (exponentially more eccentric) films.
Star Trek is good, but anyone with at least a couple gumballs worth of taste knocking around in their useless skull would easily identify Khan as the better film. Whathisfuckingname (he was that memorable) from Fuckinstabyouatopia is a quivering worm compared to the mighty Khan! No contest, baby!
Would love to see Heat in the theater again. I went to see it two days in a row when it came out--and I think that's the only movie I've ever seen twice in the theater.
