Wot no Thomas Newman?!
Best soundtrack ever - Shawshank Redemption
Also great work on American Beauty (but only 2 tracks), Erin Brockovich, Finding Nemo etc.
Agree with Moulin Rouge - I made up my own compilition from the best bits of the 2 CRAB, the film itself, and the extras on the DVD. I even did a complicated mix of Your Song from three sources to get the definitive version... some would say this is a bit sad, and of course they'd be right.
Run Lola Run is good, but dangerous cos if you play it in the car you end up doing about 140mph. Ditto The Matrix.
Honorable Mentions:
Gattaca
The Truman Show
Out of Sight
And for pop, liked Dumb and Dumber!
