You can make five massive hits in a row and still not get cast by the directors you want to work with, doing little movies. There are no guarantees. I'm trying to sign up and do movies that I'll be proud of, if it's my last one. That's how I think about it.

I was quite intimidated by Ralph Fiennes. I didn't really talk to him while I was doing Harry Potter and the Goblet of Fire and the only thing I did with him was when he stepped on my head. Then I went to this play and he was there. And this girl said, “you've worked with Ralph Fiennes haven't you, Robert?” and I was like, “well, no...” and Ralph said, “yes, I stepped on your head.” And that was the extent of our conversation.

Never trust a guy who plucks his eyebrows.

They [Barnes Theatre Club] were a very good group, and for some reason when I finished the backstage thing, I just decided to that I should try to act. So I auditioned for Guys and Dolls and got a little tiny part as some Cuban dancer or something and then in the next play I got the lead part, and then I got my agent. So I owe everything to that little club.

I was obsessed with Eminem when I was younger. When he first came out I was about 12 and fanatical about his 'Slim Shady' CD. I think he's a genius.

I put a flower in someone's locker when I was 15 years old. This girl, called Maria. Maybe I was 14. She actually thought it was from someone else, and the other guy claimed it as well, which was just great.

I was at a small private school in London. I wasn't very academic. My dad said to me, 'OK, you might as well leave, since you're not working very hard'. When I told I him wanted to stay on for my A-levels, he said I'd have to pay my own fees, then he'd pay me back if I got good grades.
