On her perception of the royal family after starring in The Crown (2016): I wouldn't say it changed, but it definitely deepened it, and gave it a human slant that I'd never considered before. I thought she was just the Queen and he was Prince Philip, and that was just who they were, without thinking about them as a mother or a father or daughter. So, it's been really interesting to try and understand them as human beings. And when you see what they've been through, it's relatively easy, to be honest. I have a huge amount of respect and understanding for them.

I hate having to pose for photos. It's just so embarrassing. Everyone is expecting you to know what to do because you're an actor, but I haven't a clue.

I love home, any home really - my mum's, and of course my own. I love eating food there and chilling in bed with a cup of tea.

I've worked in supermarkets, put tags in baseball caps and provided security during Wimbledon, but I never thought acting would be something I'd be any good at, or make a living from.

Growing up, I was obsessed with Leonardo DiCaprio.

I'm lucky I have a fast metabolism... my whole family does... everyone's got a lot of nervous energy so we burn it off.

If I was working nine to five, acting would be my hobby... I always feel like maybe I should do an Open University degree. But I'm never going to.

I wouldn't have been able to go to drama school when I was 19. I don't think I was even conscious of life... I was like a zombie. But when I finished uni' I just realized... just go and do it, stop being a knob.

I've seen Pride and Prejudice (1995) about 4,000 times. I'm not joking: I know every single line.

I am always so envious of people who do whatever they want.

[about her "Macbeth" co-star, James McAvoy] The funny thing is you would never ever ever think the man is this movie star. He's just so down to earth. He could turn round to me and go "Your accent is shocking!" I have to remind myself to actually stop looking at him.

When I got the audition for "Macbeth", it's awful to say it but I can see what leads her to do what she does. Her husband's destiny has been proclaimed and she says "You've got to meet it." Which women do all the time.
