Josph writes: I found this on a Clint Mansell (‘Requiem for a Dream’ composer) website, it deals with the music for the new trailer.

It’s been the talk of the net for the past week or so, and we can officially reveal the truth! the main theme from requiem for a dream has indeed been re-recorded for use in the lord of the rings: the two towers trailer.

Clint is really pleased with the results – three short pieces were re-recorded with a full orchestra and choir for use in different trailers. the theme is unlikely to be used in the film.
