I do find it strange, doing magazine shoots. Photographers always go, 'Why don't you like to have your picture taken? That's what you do for a living anyway. Just pretend you're acting. It's the same thing!'

I actually went to drama school at the Royal Scottish Academy of Music & Drama in Glasgow, so I stayed in my home town the whole time. However, I see more of my friends now than I did then. It's strange.

I've never worked as hard as when I was at drama school. It's the most professional environment I've ever been in.

I kind of embarked on a fruitless search to find information about my character, Frederick Aiken. And it was fruitless, unfortunately, because there's so little about him.

That's the main thing that attracts me - characters who have big journeys. I like playing those people.

I'm taking probably the biggest risk of my career in playing the part in Filth. If you stop taking risks, then you get bored, or you just keep playing the same part, over and over again. Eventually audiences get bored of that, as well.

I am a nerd, but I don't dive head-first into any fiefdom of nerdiness, except for maybe 'Star Trek.'
