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.

When people feel good, they look good.

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.

I think I'm up for not trying to play a literary heroine. I think I'd rather just do someone that has just been created in a script, rather than in a book that everyone knows and loves. The difficulty with it and the reason these characters are so loved is that every woman and man that reads it understands it in a different way. They're so relatable, but different aspects will be drawn from different people.

I think that period dramas just need zombies.

I don't like seeing celebs looking too skinny, I love it when they look healthy and comfortable in their bodies and embrace their curves.

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.
