In Britain, you do your job. When you do an American TV show, there is a sense of being one with the crew, and there is a leadership element, which was a learning curve for me because it is very different culturally. In Britain, you just do it, leave and say, 'Thanks.'

We're in a world where masculinity, especially with these big spectacle movies, is often pushed by rippling six packs and forcing an image down someone's throat trying to prove masculinity. Whereas I think true masculinity comes from having a strong sense of self.

It's frustrating we still don't see more movies featuring strong women.
