What film is the music from that Warburtons advert from?

[Bomper]

You know, the one where they burn the loaf? I always feel really sad when I hear it and remember it's from a film but can't remember which one.

Samuel Barber, Adagio for Strings

I always think it's the calm section from Tiestos version and am just waiting for the fist thumping bass to kick in.

It's from Amelie, Platoon and Elephant Man
