When Tobey Maguire was a kid, he had to start off his career by working a few uncredited gigs as an extra in such projects as The Wizard. He eventually graduated to small bit parts where he would actually get a few lines of dialogue, such as in this 1991 episode of Roseanne, which he did when he was 15. Of course, now whenever I see Tobey Maguire in an eating establishment, I expect a car to come flying at his head.
