A little showbiz never hurt anyone.

I found American actors quite scary because they're brilliant actors and brilliantly funny, and they never stopped once you wound them up... off they went and they just deliver fantastic stuff.

I haven't played Doctor Who since I was 9 on the playground.

I'd say, don't listen to what anyone says: you're good. Go put your anorak on. Get your thick bottle-top specs. Draw your little cartoons and your comics and keep writing to the BBC.

When I first came to London, I loved hanging around in cafes, smoking, scribbling, dreaming. It was life-affirming and fun.

There is no greater symbol of the artistic spirit of Scotland than the Mackintosh building. But more than that it is a symbol of where art belongs, rising as it does out of the heart of a great city. A mighty castle on a hill, it is a part of me, and of all Glaswegians.
