Paul McCartney featured on "Mood Indigo" movie soundtrack

Director Michel Gondrey says Paul McCartney played bass - unbilled - on the the soundtrack of his new film, "Mood Indigo."

The movie, which stars Audrey Tatou of "Amelie" fame, is a fantasy/romantic comedy released in France last year. It's showing in select U.S. and U.K. theaters now.
Gondry: And there is this one thing that no one ever knows, is that Paul McCartney plays on the soundtrack. He plays a bass in the score, in half of the tracks.
Gondry directed the video for Paul's "Dance Tonight" video in 2007.
