Emma: I think it’s been quite frustrating for Tom in the fifth and the fourth and the third films because Tom had so much more to give. I was so glad when I read the script that he had such a big role. It’s like seeing a new character because Malfoy becomes so much more complex, conflicted, you see him struggle with his own identity, and the task that Voldemort’s given him.
