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.

It took me a while to warm to the '20s costumes on 'Downton.' I love it when women accentuate their curves, and that era was all about hiding them. The shapes they wore then were in tune with female empowerment. Cutting off their hair and hiding their busts was a way of saying, 'We're equal to men!'

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

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

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 love clothes but it's a struggle for me to get out of jeans and a baggy jumper.
