I've realized as well after five years of being on the road that if I'm going to four or five months of my life to something even if I'm overpaid, it's four or five months of my life away from home, away from my son, away from family and friends. I better believe in it on some level even if it's a big movie.

I'm enjoying [my career]. If anything I'm aware that the pressure of the first, I suppose, six or seven years I was in America - I mean that energy of having such a rapid and ascending celebrity - it's not there anymore. It's the end of that chapter and now I'm just enjoying the work probably more than I ever have and yet I'm simultaneously less attached to it I think, which is kind of a strange state of grace to be in.

I certainly do believe in monogamy. I don't believe that it's for everyone. I don't believe that marriage is for everyone. So much of life is begging to be chosen how it wants to be lived. Much more than most of us realize.

I count 'Underworld 4' as my training period for 'Total Recall.' I do think it was hard because I didn't realize how tired I was. It is quite a lot to sustain that kind of physical work over nine months altogether and by the end of it, I definitely felt like I had aged quite a bit in that year.

I am more comfortable doing a drama.

I love working with horses. People say you shouldn't work with animals and children; that's wrong. You must only work with children, because you only work eight hours a day and I love working with animals. Animals have an honesty that human beings reach to find in their lives at the best of times.

I never think I'm capable of any of [action movies]! I'm always terrified, but luckily on this one it was directed by my husband [Len Wiseman]. 'I can't possibly do it. I'm too scared, I can't do it.' He says: 'Go on. DO it!' So it is shocking as I'm not one of those people who finds that stuff easy.
