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.

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.

If you're in the so-called public eye you have to watch your P's and Q's.

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.
