what film is this song in?

does anyone know where this song is from? It's called "mad world" by gary jules(I think)
It was also done by tears for fears but this is a very slow version.
I know that I've heard it at the end of a film before but I can't remember which one and it's really bugging me
any idea anyone?

Donnie Darko.

Great teenage angst - stuck in time warp - about to get to where I know I am going to die in a freak accident flick.

of course!!!! many thanks M.A.
excellent film with a great sound track. i'm gonna have to get it on DVD sometime.
