Alan Rickman, who was mentored me a lot. He was very keen to offer his opinions on stuff. Not in a pretentious way. Not in a patronizing way.

I think screenwriter Steve Kloves does such a difficult job. And he does a bloody brilliant job, too. Transferring these Harry Potter books into films and making them coherent is one thing. But making them entertaining, as well, is quite another... He does a tremendous job, and he gets a lot of stick. And it's really unfair sometimes, and I challenge anyone else to do the job he does.

The reason I feel bad for Steve Kloves is because he doesn't enjoy cutting things out. He's not sitting there with scissors, just laughing maniacally, going, "Ahahaha." He doesn't like doing it. The stories mean so much to him. But it had to go. And David kept saying, "We're gonna try, we're gonna try, we're gonna try" all the way into the shoot until the very last days, when he said, "Sorry, it's just not gonna work."

I did enjoy theater. I actually do prefer making films and television, but it was a learning experience for me, because I got into television at 5 and film at 11, and theater was something I completely bypassed.

You have to prepare for the unexpected. You have to be able to react to things that don't necessarily happen every night, or aren't supposed to happen every night. And you have to react to it in character.

I must confess I don't own Harry Potter DVDs. My parents do. They have them all. And they like watching them. They've got all their home videos done in HD quality! They love it. But I struggle very much. I'm very self-conscious as an actor, anyway. I don't like watching my own performances, even in this recent one.

I'm not a big fan of people knowing too much about me.
