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.

I want to be with my wife. Sitting on a deckchair, sipping some tea, and reading books in a retirement home, in a beautiful and warm place. I'm a romantic guy.

I never ever would have thought initially it would have been someone like Pierce playing Charles. I think he has an innate likeability to him, as soon as you meet him he's very, very charismatic. Charles, on the page, was someone who's very domineering and quite a negative character, and Pierce just by being Pierce can change the whole dynamic of it, which made for a much for interesting relationship. He's a really nice guy.

It's a little bit over the top. I feel the same in my head I guess. I was quite a paranoid person anyway, so it doesn't really feed well when people are looking at you. I'm not really in the right job. I don't like having my photo taken. I don't like the attention.

Up until I was 12 my sisters used to dress me up as a girl and introduce me as 'Claudia'! Twelve was a real turning point for me as I moved to a mixed school, and then I became cool and discovered hair gel.

I'll probably go to London and hide.

The special effects team designed everything, which basically allowed me to stand on a green box and look and stay relatively expressionless and all these machines did the acting for me. Just the way I like it (laughs)
