Fear is really powerful; it's really useful to me.

I was brought up by my grandparents. So people go, oh, what was that like? That must have been hard. And you go: No, it wasn't.' It was just completely actually normal because the new norm seems to be whatever you make of it, doesn't it?

As I get older, I want to do more films for kids because they're the best audience around. Just putting a smile on a kid's face is the best thing.

I take a lot of pride in being myself. I'm comfortable with who I am.

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'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.

It's quite liberating to have a director stand beside the camera and say: "Do this now, and do that now..." It's also a bit sordid but it liberates an actor, I think.
