trailer link: http://www.imdb.com/video/screenplay/vi4254662937/

It's the first piece of music in the trailer. I checked on soundtrack.net, they only list "Millenium Actress (2004)": http://www.soundtrack.net/movies/database/?id=17148

if this is it, then the music would be specially produced trailer music. Immediate music released a few CDs, maybe it's on one of those..?
