I never thought I'd be one of those old hams who favours theatre over everything, but I'm getting that way. Telly and film seemed more fun when I was younger; turning left on planes and washing up in nice places. But there are things that you only learn in theatre.

Careers are what they are, they don't make any sense at all when you look back. We're not in charge of them.

The power of telly is surprising. If you're in a six-part series, you're famous while it's on - people point in the street. Two weeks later it all goes back to normal.

I'm not a sci-fi lover; I wasn't from the start. So perhaps I miss that passion for other worlds, other dimensions, that sort of scope and that magnitude of storytelling; that's not my thing though I meet plenty of people whose thing it definitely is.
