Vin Diesel

The Iron Giant ("The Iron Giant")

Though Diesel frequently comes across as an arrogant blowhard in his live-action films, he gives an extraordinary vocal performance in this acclaimed 1999 Brad Bird animated family film. The Iron Giant is a 50-foot robot with a deep, gravelly voice from outer space whose bark is far worse than his bite. The gentle giant is "adopted" by a lonely 9-year-old boy named Hogarth. Though the film earned enthusiastic reviews, it didn't catch on at the box office. (Warner Bros.)
