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 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.

The first Disney movie I saw I think was 'Snow White.' I loved all the Disney princess movies.

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.

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

Playing a Disney princess is the most amazing, unbelievable thing and on the other, it's completely terrifying. I would say it's a cocktail of every sort of emotion. Princesses are great role models, they teach you about grief loss and have big hearts.
