Everyone on the set has a mobile phone, and I found by pushing a few buttons, they could be programmed into different languages. I fixed Robbie's Coltrane to speak in Turkish.

My favorite phrase, that a friend of mine who worked on the Potter films and was a lot older than me would use in front of me, and I picked up from him many great phrases - the English have a lot of great idioms for sweating. I don't know why that is. But that's what we do. I feel like it's particularly our country; probably everywhere has a lot of idioms for sweating. He always said, "I'm sweating like a glassblower's asshole," which I always found an incredibly strange and yet vivid image.

The stories I'm interested in are challenging ones, and maybe that requires a little bit more of you. I love my job and I want to earn the right to do it every single day.

The one piece of advice I would give to any actor is, if you want to go out on the street without being recognised, without even being looked at, go out with a 6ft 8in beautiful transsexual. No one gives you a second glance. Especially when you're 5ft 5in.

No. I can quite happily say someone is handsome, good-looking, and I can see why someone would want to f**k them, but I've never felt that way about a man myself. There is that moment in your late teens when you ask yourself the question, 'Am I?' but I wasn'tWell, this year I have a talent crush on Ryan Gosling. I think he's fantastic and(ahem) you know he'd be nice afterwards. He seems smart. If I was gay, I would go for a smart man.

I'm not a religious person. My mom was of Jewish blood and my dad was Protestant.

I mean I've seen 3D films so far and I think it's a long way to go before they replace actors. It's a funny thing with 3D, I haven't quite got it yet. Yet.
