Ashton Kutcher and Seann William Scott Star in <em>Dude, Where’s My Car? </em>(2000)
Two years into his TV gig, Kutcher got his first big screen movie role in the stoner comedy Dude, Where's My Car? Already adept at playing stupid, Kutcher got to show off his talents on a global scale, and the dumb comedy became a box-office hit, opening new avenues for him.
