Watched "The Life Aquatic" DVD the other day, and thought it had a pretty cool soundtrack. Essentially all of the music is David Bowie songs, mostly older Bowie. A couple/few are the original Bowie tracks, but many are more or less "performed live" by a character in the movie - in Portuguese, no less!
If you haven't seen the movie, this bears a bit of explanation: The movie is more or less about a Cousteau-like (only much stranger) ocean explorer-type, named Steve Zissou (played by Bill Murray). The cast is pretty interesting - others in the film include Owen Wilson, Willem Dafoe, Cate Blanchett, Jeff Goldblum, and Angelica Huston (pardon any spelling errors). One of "Zissou's" boat crew is constantly strumming on a guitar, and singing songs in the background in Portuguese - which you recognize after a while as being all Bowie songs, mostly from Ziggy Stardust. One of the actual Bowie tracks used near the end of the movie is "Queen *****" off of Hunky Dory. I'd forgotten what a great song this is, despite being only "three chords and a cloud of dust".
As for the movie itself, it was pretty funny, but in a weird, interesting way - sort of in the vein of The Tennenbaums (same director, maybe?). For some reason I really noticed that the cinematography was great, as were the computer-generated underwater scenes with a variety of invented marine life.
