I see myself doing Harry Potter films as long as I'm enjoying it and as long as they are going to challenge me as an actor. I want to be an actor - it's my aspiration - so I want to do other films. I want to write something and I want to direct something!

I think any man who says he has never had an awkward moment with a girl, is a liar or he's delusional because he's sitting there thinking he is doing really well and the girl is thinking "Who is this man and why is he talking to me?"

Some actresses are just insane. I've never worked with a nasty actress - they're all absolutely delightful. But completely barking.

Potter for me is something that's been giving me these amazing opportunities to start a career and learn while I'm doing, which is the best way to learn.

I don't think there's anything that I would really baulk at doing on-screen. I don't think so. I've got certain pet peeves about writing... my pet peeve about reading scripts is when they give you a line reading and there'll be a line but next to your character's name it'll say 'very angry'. But I'm like: "Well, I'll decide that actually!" So, there's little things like that. That's a slight pet peeve.

My dad's got a brilliant eye for scripts 'cos he's a literary agent. He and my agent read a load of scripts and filter them.

I've always had, like, from the age of about 11, I've had such an intolerance for bad behaviour of actors that I don't think I was ever going to be that person.
