A young Brit girl with no theatre experience decided to take on an iconic American role on Broadway. Maybe I should have thought that through?

My life is unrecognisable compared to what it was - 'Game of Thrones' has opened doors that were never there before. But it can be dangerous to see it in those terms, I think. It's best to take it as it comes and work as hard as you can, and hopefully the other things fall into place.

There are no captions on red-carpet photos that say, 'This girl trained for two weeks, she went on a juice diet, she has a professional hair and makeup person, and this dress was made for her.' I just wish they'd say, 'It ain't the truth.'

My dad took me for an audition once, to show me, OK, you want to be a child actor, this is what its like. I sang a folk song about donkeys on this West End stage with this big director, and there was a queue of 200 girls all singing Memory. I was terrible. Terrible.

My father always says, ‘Never trust anyone who has a TV bigger than their bookshelf.’ So I make sure I read. Back at home, I just put up a massive bookcase and asked everyone I know and love to help me fill it with their favorite books. It’s been quite nice because I’ve learned a lot about my friends and family from what they’ve been giving me. A book says a lot about a person.

I looked around one stage school when I was maybe nine. It just scared the bejesus out of me. I was incredibly open, and the girls seemed fierce and determined.
