You feel quite strangely secure [doing any kind of series]. It's the opposite of how you're supposed to feel doing a movie.

It's insane. I've had girls throwing themselves at me since the hype started. Now the film's out I can't walk down the street without being pounced on. All my life I've hated crowds. Now I only have to step outdoors and I'm at the centre of one. It's very cool but it's very uncomfortable too.

I aspire to be Jack Nicholson. I love his every single mannerism. I used to try and be him in virtually everything I did, I don't know why. I watched One Flew Over the Cuckoo's Nest when I was about 13, and I dressed like him. I tried to do his accent. I did everything like him. I think it kind of stuck with me.

I like being a part of David Cronenberg’s world, I feel very at home there

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.

Everyone used to chuck snails at each other at school, and I used to try and save them. And not only did I get in trouble for it, I got suspended for doing it. For saving the snails I kept about four or five hundred of them at the back of the class -- in Snail Land. We were like six or seven or something, people didn't even realise what they were doing. I had a strange compassion for snails. And the teacher just chucked them all in the trash in the end.

I will keep that a secret as it was so indecent I doubt she was in her normal state of mind when she made it.
