All these things, social media or [smart] phones or the things that distract us from each other, are fairly new. They're all fairly new inventions, and I think we're in a stage where we sort of as a whole have gotten these new toys and we're just obsessed with playing with them. I feel like after a period of adjustment it will inevitably be a regression from where we are now.

My favorite phrase, that a friend of mine who worked on the Potter films and was a lot older than me would use in front of me, and I picked up from him many great phrases - the English have a lot of great idioms for sweating. I don't know why that is. But that's what we do. I feel like it's particularly our country; probably everywhere has a lot of idioms for sweating. He always said, "I'm sweating like a glassblower's asshole," which I always found an incredibly strange and yet vivid image.

My dad grew up in Banbridge, Northern Ireland, desperate to get to London. I grew up in London, so I don't know what it's like to yearn for the big city from a small town.

My dad's got a brilliant eye for scripts 'cos he's a literary agent. He and my agent read a load of scripts and filter them.

I take things in better when I'm allowed to talk, and respond, and engage and move around a bit.

Stage is much more intimidating than going before the cameras, because you can really screw up, and can't do a retake.

I've worked every day since I was 10. I don't know how to do anything else. There is nothing else I'd rather be doing.
