Yeah loads of bruises and welts, usually around the hip, arse, thigh region and elbows. Elbows got knocked up big time, but it was so much fun. I hadn't done a meaty action film in seven or eight years, so it was fun to explore that aspect of storytelling again.

The sea always offers up incredible stories of survivors' fortitude. Myths of a lot of countries have variations on that.

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.

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 think that is what you want to do as a cinemagoer - to experience something fully. Some things don't let you experience them fully. It may be your own preordained prejudice where you can't experience them fully. But when you come out of the cinema having felt, thought, and experienced your way through two hours, that is a really cool thing.

It's not that I'm stupid. I just don't think sometimes.
