"Looking for supermodels takes up my time," this Londoner says in jest. His career, however, is no joke. A virtual unknown (he had a small part in Vanity Fair), Robert, 19, scored the role of Cedric Diggory in Harry Potter and the Goblet of Fire. In the latest installment, Harry and Cedric getinto wand-to-wand combat in the Triwizard Tournament. "cedric is the guy who makes the right decisions all the time," Robert says. It's a great gig for a newcomer who's not sold on his profession: "Sometimes I think, 'To hell with acting,' and then I realize I could be working at a shoe shop," he says. "Acting is much cooler." Supermodels, take note!
