Helena (Bonham Carter) is one of the coolest kindest women I've ever met. We had so much fun. She has the best sense of humor. I loved her fairy godmother. It came at a point during night shoots where I was exhausted. It was trippy, weird and cold ... and then Helena showed up. It was like this bright light on the horizon; it was wonderful.

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 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 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.

Boarding school in Tring was a bit of a bubble that burst when I went to Hackney to go to drama school.

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.

When people feel good, they look good.
