When you're filming in Russia in Catherine's Palace, and you're in the real place where the Tsar's ball really happened, all those years ago, it does so much of the work for you. It's so vivid. You escape into this different time through the costumes, the sets and the atmosphere.

I am absolutely desperate to do an action movie. And not to blow my own trumpet or anything, but I actually think I'm good at it. I did it all. I was really into the routines and the choreography. I used to dance when I was younger, and so I think that came in handy.

I think it's probably best to work out in the morning to get it out of the way. My ultimate top tip is to drag yourself, even if you have to roll yourself out of your bed and in to a sit-up - it's really not that bad once you start.

When people feel good, they look good.

I can only show what I have received from the characters. That's what's scary because you're never going to be everyone's taste and you don't want to let people down. But, I can only do what I can do.

I really want to play interesting roles, but you want to work, so it's a balancing game.
