Listen, acting is not surgery, it's entertainment. You're doing something to hopefully move people, to make them laugh, to transport them. But actors are vulnerable, and the reason we're vulnerable is that we're always trying to recreate human behaviour.

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.

I'm fully aware that I am a lucky, lucky man. This Oscar belongs to all of those people around the world battling ALS. It belongs to one exceptional family, and I will be it's custodian and I promise you that I will polish him, and wait on him hand and foot.

My first film, 'Like Minds,' was with Toni Colette, who was extraordinary. I mean it was basically a mini-masterclass for acting on film at a time when all you could probably see were my eyebrows bouncing up and down on screen.

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.

Making 'Birdsong,' on the one hand you have how prestigious it is and the reputation of the book, which is something that's an extraordinary piece of work. Sebastian Faulkes is a genius. So you feel that responsibility when you're portraying that character that he's imagined and millions of readers have pictured.
