And the most important thing - apart from telling a good, believable story, and being a true character - is to be someone the audience will care about, even if you're playing a murderer or rapist.

Any scene that involves stripping off is hell. You just know it's going to take a day or more to get it right. It never gets any better and it's always uncomfortable, and all you can do is grin and bare it. I just pray it's never gratuitous and that it doesn't look so fake that all you hear in the audience is, 'Well, that's not really her, is it?'

Eating at home is important for us, because we eat out so much when we're away. When I'm at home I cook a lot and we eat pretty healthily. I'm not a massive vegetable fan - I've got better since I discovered how to undercook them.

I've been on sets where the turnaround is so fast and the budget so small that the actors have been asked to speed things up and save money by changing in the public toilets. There's no room for vanity at times like that. It's the best way: get on with it!

For me personally, everything is on a kiss.

I'm in a really good place. I used to be a right worrier, but being in a settled relationship has made a massive difference. I was on my own for three years before meeting David. I'm very happy with him, he's a fantastic man. But you never know what's around the corner, so you just hope for the best.
