At the end of the day, it's all one version of telling a story. I treated this as if it was a two million dollar independent film. I did a lot more physical work than I'd probably have to do for a two million dollar independent film with four months of training and stuff. But as far as the character's psychology or emotional life goes, I treat it just the same.

I think people are propelled towards violence, and what propels them is much more interesting than the actual act of violence itself.

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

I've started films like Miami Vice where I'm in really good shape and I look back on that film and see the moustache is bigger as I've got a larger face.

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.

When I read the script it was extraordinary and to work with Yorgos [Lanthimos] again was amazing.

I'm not keen on cars and motorbikes. I tried to be a biker, but it wasn't me - I bought a Harley-Davidson and dumped it.
