In “Happy Feet,” Elijah Wood plays a dancer in a world of singers — It’s just the sort of twist he loves. Having taken on a variety of eccentric projects, including “Eternal Sunshine of the Spotless Mind” and “Sin City,” since starring in the “Lord of the Rings” trilogy, Elijah Wood finds himself at it again. This time he’s a dancing penguin in director George Miller’s eco-friendly animated film, which turns on the unique mating calls of emperor penguins. Wood, who also stars in the upcoming ensemble film “Bobby,” gives voice to Mumble, the sole dancer among a tribe of singers. (Costar Robin Williams has called it “March of the Penguins” meets “Riverdance.”) [More]
