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

I'm so lucky to have worked with Burt Lancaster, who I remember was one of the first people I'd heard swearing in a really interesting way.

I think the most extraordinary thing about fans is the level of excellence that they show in the work that they do. I mean, if you go onto the internet and see some of the fan videos that have been put together, they're just extraordinary; they could be programmes in their own right.

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'm a huge fan of The Sopranos, and suddenly, you find yourself going one-to-one with this guy who you've been watching for years, watching every flicker in his eye and every detail on his face.

If you actually have to engage with somebody who's superior to you and actually battle with them, struggle with them, I think it's more interesting, and funnier for the audience.

The older I get, the more I think lightness of touch is an incredibly difficult thing to do.
