WATFORD, England — In Harry Potter and the Half-Blood Prince, the enduring teenager dispute among the bespectacled boy wizard and his bratty blond nemesis, Draco Malfoy, becomes something much nastier.
though the two have been at loggerheads since Harry started at Hogwarts, things have gotten downright deadly. Harry and Draco's dealings goes from annoying taunts to critical roles in a deadly battle that alters the course of their wizardly world.
And the actors, no longer boys, are up for the manly confronting in the sixth episode, opening in theaters Wednesday.
"It was youngster opposition before," says Daniel Radcliffe, who plays Harry. "It was playground insults. It was all pretty tame stuff. And then suddenly this time 'round, it actually gets nasty. Draco is turning into something much more meaningful and menacing."
But the aura of menace is nowhere to be found between takes on the convivial Potter set, a previous airplane hangar about an hour outside London. Longtime co-stars have come to regard one another almost as family, having starred in five earlier Potter films mutually.
