I think sometimes it's sort of easier to be playing a role based on a real person because there's quite often a lot more information, you're not making it up, it's there in books, it's there in research form. But really the questions you ask about the character, and why people behave, and where they come, and how they've ended up in the places they've ended up are the same.

I went through voice coaching. I was absolutely terrified. I thought my knees were going to buckle, and the first couple of takes I sounded like a pubescent boy. I didn't realise I was going to have to do it live.

I love costume dramas, I love performing in them, because in a funny kind of way, you feel more free. You know about the period, you can read the books, you can see the paintings, but you've never actually going to know what it was like. You can kind of stretch those boundaries a bit.

The thing about great fictional characters from literature, and the reason that they're constantly turned into characters in movies, is that they completely speak to what makes people human. They're full of flaws as much as they are full of heroics. I think the reason that people love them and hate them so much is because, in some way, they always see a mirror of themselves in them, and you can always understand them on some level. Sometimes it's a terrifyingly dark mirror that's held up.

I think I always disappoint people, because they always expect someone very pretty. Very done. There’s so much pressure to be thin, blonde and busty. I’m skinny, but even I couldn’t fit into some of the clothes in L.A! In a funny kind of way, I think you create it yourself. I think it’s much better to go with the flow and embrace your body, whatever shape it is, and just be happy.

When I was about 5 I think, I desperately wanted to be a pirate and have the hat and everything.

I am a slow reader. I always loved words, which is a strange thing given that I couldn't actually read them
