'Music in the American trailer . . . '

In the American trailer for this film there's a a very beautiful piano piece that's used. To the best of my knowledge it's not featured anywhere in the film itself, but I was curious if anyone might know if this piece is written by the two composer of "The Terrorist" or if it's a drop-needle. Any help would be most appreciated.
