I just hate the idea of being well known. I know that is almost impossible if you're an actor who has done okay, but I've always fought against it.

A child did approach me in a restaurant in Cornwall, but he thought I was Gandalf.

Oh yeah, I'd love to be a comedian. I've done a lot, but always in the confines of plays.

There were no spells at my school, just a smack in the mouth.

Every part I play is just a variant of my own personality. No real character actor, of course, just me.

There's no subtext in Harry Potter really; it's all magic, anything can happen. Why do I say this? Because it's a magic spell. It's quite nice in a way. There is a real freedom to it.

Yeah, I like causing trouble. It's the teddy boy in me. I used to be a teddy boy. Feeling slightly inferior and wanting to cause a bit of bother and get some action going on in the room rather than get bored stiff.
