I was brought up in a way that when you're at a dinner party, you don't grab a chip unless it's been offered to everyone else. It's the manners of being brought up by English parents.

I've always felt that if you back down from a fear, the ghost of that fear never goes away. It diminishes people. So I've always said 'yes' to the thing I'm most scared about. The fear of letting myself down - of saying 'no' to something that I was afraid of and then sitting in my room later going, 'I wish I'd had the guts to say this or that' - that galvanizes me more than anything.

If you get too heavy with the nods and winks, people get a sense that they're excluded from something. If they're in screenings and everyone's laughing, and they don't know what the hell it's about, somehow you feel excluded from the party, or like you're not in the inner circle. As a performer, that's the worst thing you can do to an audience. It's fun, but you have to be very careful with it.

To make films like 'X-Men' work commercially - and also have some class - is one of the hardest things there is to do. I want to be seen to be able to cross lots of genres and still be 'fair dinkum,' as we say in Australia, which means genuine and true and, well, unique.

Now I meet people with full-color Wolverine tattoos on their backs. Thank God I did okay, because I think if I hadn't, they'd spit on me in the street.

Acting is something I love. It's a great craft that I have a lot of respect for. But I don't think it's any greater challenge than teaching 8-year-olds or any other career. In my life, I try not to make it more important than it is and I just hope that rubs off on the people around me.

Luckily, I'm not afraid to make a fool of myself.
