“For me, the 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.”

Heyman states, “Jo gave us the gift of these magnificent books and every one is a jewel. Her imagination never ceases to amaze me. Each Harry Potter book brings us new challenges and new opportunities, so coming into this movie, we were as excited as ever.”
