Beloved boy wizard Harry Potter comes face to face with Voldemort in the first cinematic installment of “Harry Potter and the Deathly Hallows.” Actor Tom Felton shared an exclusive clip of the forthcoming film Saturday with about 6,000 convention-goers at Comic-Con. Many of them camped out overnight for a chance to see the footage. The clip showed Potter and his pals navigating a dark world after Voldemort and his minions overtake the Ministry of Magic and Hogwarts. It introduced Bill Nighy in his role as Rufus Scrimgeour and hinted at a confrontation between Harry and Ron Weasley. Felton, who plays Draco Malfoy, said the entire cast is “incredibly proud” of the last two films. He said it was tough to part from his castmates on the last day of shooting, adding that star Daniel Radcliffe “cried like a girl.” The movie opens in November.
