The American Astronaut is low budget SF that Benny recommended -- it's a little too self-consciously campy for my tastes but I liked the way they use music in it Bittorrent
I didn't like It's All About Love much (I watched it b/c I liked Dear Wendy a lot by the same director, Thomas Vinterberg) but I enjoyed a moment at the beginning where some characters notice a dead guy at the bottom of the escalator they're on. The body jerked slightly as the steps slid by under him, and they just step over him and go about their business -- apparently people are dying all the time of some heart ailment. It was nice mix of the grim and the familar.
Wim Wender's Until the End of the World is a really interesting, different sort of sci-fi flick. Great production design, use of music and tone. The kind of film that stays with you well after you've seen it.
Craig W. mentioned that The Soul Investigatoris a Toronto art-SF film made about 10 years ago. Can't seem to find it anywhere, did a call around the usual vid stores but no go.
He mentioned Cosmos is a movie that has several segments directed by different people.
