The Curious Case of Benjamin Button, a new film starring Brad Pitt (due out on Christmas Day), tells the story of a man who ages backwards, starting life as an old geezer, and dying as a child. This new preview for the film uses Arcade Fire's "My Body is a Cage," which for obvious reasons, makes it a great song to use in accordance with the film. It's looking like that film could be pretty interesting, and hoever's running the ad campaign certainly knows their music. [Stereogum]
