Not only did U2 record a new song for the animated film "Sing 2," but Bono voices one of the characters. He "plays" Clay Calloway, an aging lion who was a rock star legend. Scarlett Johansson plays Ash, a porcupine punk rocker, and her version of U2's "I Still Haven't Found What I'm Looking for" looks like a real showstopper. Who knew a porcupine had such chops! The movie opens December 22 and the kid in me can't wait! (photo: Getty Images)
