At this week’s U.S. premiere of Harry Potter and the Deathly Hallows: Part 2, Emma Watson may have summed the movie up best: “It’s so good,” she said from the red carpet. “It’s so good! It’s epic times four. It really blows your mind.” Also blowing our minds this week is how much the Potter kids have transformed since the franchise began ten years ago. Emma Watson turned into a fashion plate. Daniel Radcliffe blossomed into a man with the confidence to conquer Broadway. And Matthew Lewis got hot. When we asked producer David Heyman what strikes him most when he sees decade-old pictures of the cast, he told us: “How innocent they were, and yet in some ways, how they remain very much the same very humble, decent people they were back then. Yesterday, a 6-year-old girl said to us, ‘Is the magic in the films real?’ And Emma said, ‘There was magic in the making of these films, and as Dumbledore says, ‘Just because it’s in your head doesn’t make it any less real.’ I thought that was a pretty collected, composed response.” For more farewell quotes that will make you cry, click through our slideshow.
