In a new interview with PEP Dan Radcliffe, David Heyman, Michael Gambon and David Yates talk Harry Potter and the Half-Blood Prince.

“For me, the Harry Potter films have always been about a loss of innocence,” says Daniel Radcliffe, the actor behind the title character, who can perhaps no longer be called the boy wizard. “When Harry came into this world, it was all just amazing and brilliant and kind of pure. But as the films have gone on, that’s totally disintegrated, and he’s realizing that the wizarding world has just as many, if not more, challenges than the world he grew up in before.”
