As a runner on a film, you are the lowest of the low, and yet you have incredible access to everyone. I can totally imagine that for actors in the middle of a Hollywood bubble, all they really want is a sense of normality, and that gopher can be a tap for that.

The fear of messing up is what makes you work harder!

I have this horrific thing where I'm really bad with names and faces. I have an appalling memory. Someone will come up to me in the street and go, 'Eddie!', and I'll try and give myself time by going into overdrive, 'Hey, hi! Nice to see you!' and start a whole conversation because I can't distinguish between who I know and who I don't.

A lot of people think theatre must be much harder work than film, but anything histrionic or superfluous gets seen on camera so you have to work to distil it into a complete sense of what's true.

Actors who perhaps are super-confident and have absolute belief in themselves I always admire, because I can't really be like that.

And you can't complain about kissing Emma Watson. Isn't that what everyone in the world wants to do? I've known Emma for a few years. She's this amazing capacity of young and vibrant and brilliant, but also a bright, intelligent old soul.

I think all actors have a similar deal. You want some people who understand. Although it looks great - and is great - there are also shoddy moments when you feel really rotten, and when it's going well, you're not allowed to complain.
