The Canadian indie pop group The Arcade Fire has signed on to score the new movie from the producer of Donnie Darko. The Box is based on the short story "Button, Button" by Richard Matheson and stars Cameron Diaz and is produced by Richard Kelly.

In case you were living without electricity or running water in 2001, Donnie Darko is a strangely awesome movie with a passionate cult following. The soundtrack threw the haunting Gary Jules cover of Tears for Fears' "Mad World" into the pop stratosphere.

However, soundtracks are one thing and scores another. A score is the background music which helps bring forward the desired mood of the viewer during a scene. Surely different than producing a song with a beginning, middle, and end. In producing a track the audio is the central experience; with scores, the music supports and contributes to the visual experience.

What other indie-popsters have scored movies? Have they done it well?

My Google searches came up empty. But I did find this little snippet example of Donnie Darko scoring. (It's a weird scene. The whole movie is like this.)
