Where You’ve Seen Him: Rupert Grint

The redheaded actor had never appeared on film until he made his debut as Ron Weasley in 2001’s “Harry Potter and the Sorcerer’s Stone.” Since being cast in the world’s biggest franchise, he’s made smaller movies in Britain, including the 2006 dramedy “Driving Lessons,” starring as an awkward teenager opposite Julie Walters, the actress who plays Ron’s mother, Molly, in the “Potter” series. He also played a rebellious Irish teen in the 2009 drama “Cherrybomb,” which played on the festival circuit.
