If you've been to Moscow, it's a really exciting and great city, but it still feels like you should be a little careful about which way you're going to step.

With people in corsets you need, an hour and a half in you have to give somebody something, you have to have those trays with a little bit of fruit going around or something because you get that blood sugar [dropping] thing, so it's curious because that's in your mind at the same time as you're about to say, 'I think it's about the humanity and the depth of feeling and we need to feel [Cinderella] soul expand and by the way, more cheese for the people in the back.'

After Frankenstein, I feel as if I want to make a film about somebody having a nice cup of tea.

When I'm acting, I'm in the director's hands. I'm very happy to be. I like to be focused on what I'm doing.

Helena Bonham-Carter and I sat down to talk about [Cinderella movie] and she said, 'I really want to do it but only one thing I insist on and that's wings.' She had to have wings and [costume designer] Sandy Powell didn't want wings to begin with but had to be talked around, but that was fun.

I'm just a foul-mouthed Brit.

Everything is important, but there is a weight to these big or expected things and then there is the logistics of them and it's trying to find, while you worry about for instance the ballroom scene, how do you get 500 people to go to the loo in corsets and don't cost you an hour and how do you remember while you're organizing all that to take a breath and say, 'Well the scene is about all of that and it's about Prince hand on the small of Cinderella back as well' and we need time to do that properly as well.
