What is the music in this trailer?

I never do this, but this piece is possibly the most beautiful soundtrack I have ever heard. What is the music in the 1st TV Spot Trailer for Invictus that starts at 28 seconds? Link: http://www.youtube.com/watch?v=6aA31_3cly8

28 secs to 40 secs sounds very much like a track from Craig Armstrong’s score to ‘Plunkett & Macleane’ (the track "Hanging"). Could be a licensed mix, it’s happened before; ie Clint Mansell’s "Lux Aeterna" from his score to ‘Requiem for a Dream’ was mixed later for use as a trailer song for ‘The Two Towers’. This could also be a track from a trailer music company like Immediate or X-ray Dog (in which case, check http://www.soundtrack.net/trailers periodically, eventually the song will be identified and listed there).

Thanks, hopefully we can figure out what this song is because nobody seems to know and the song is amazing.
