The 20-second bit of music in the preview isn't Williams. It's from the film POLLOCK, score by Jeff Beal. The makers of the preview have used the most lively part of Beal's score; the piece is part of a 2-minute cue that comes just as Pollock (Ed Harris) discovers what effect dripping his paint on canvas can have, an even that transforms him into THE Jackson Pollock. An amazing score worth picking up, but it's not Williams.
