Apart from earning an awful lot of money, why would you go to Hollywood?

Actors have to remind people that they can do different things, not just the same style of one role.

I've worried more and more as the years have gone on. The more you're seen to be doing well, the more stress there is. You feel you ought to consider things more, and be more fussy - there's further to fall. All these little worries.

You never know how films are going to do and it is daunting if I think about it.

Nobody's just arrogant. I've met people who are embattled and dismissive, but when you get to know them, you find that they're vulnerable - that that hauteur or standoffishiness is because they're pedaling furiously underneath.

I try to be fussy about the parts I play. I think that's quite prudent, it means you're stretching different muscles, and you're scaring yourself by doing something which is out of your comfort zone.

I think people ought to do what they feel useful at the time. If I do things because I ought to do them, I switch off.
