If I'd had fame early on, I'd have been able to abuse it in the way that a young man should.

I'm aware of the power of looks. I've wanted to play roles that have gone to much better-looking people and you just think 'Oh well, that's the pin up guy's an actor like my friend James Mcavoy, who's gorgeous on screen. I'm not that. But at least I don't have to worry about taking precious care of my face because it's my commodity. That's a great freedom. I'm not afraid of being heinous for the sake of a part

That's something I have to work on: to separate what really matters, to conserve energy by not worrying about what other people think. When I walk through that door, it's about home. If I didn't do that, I'd become consumed by one thing only and damage the people who love me. And it would damage the work.

I drag a lot of stuff round with me that I don't need.

It does get strange when you realize people will hang around for hours to get a glimpse of you doing scenes outside.

I've turned up to costume parties in the wrong costume. I've made social faux pas a plenty. I've put one foot in front of the other and fallen over.

I ate healthily, but there was no snacking, no drinking, no bread, no sugar, no smoking. Afterwards I had a pork belly roast.
