I love mysteries on television – the more psychologically complex the better.

Theres just a big group of actors in London. There are new ones coming in all the time, who are looking for work, and established actors who are interested in working and like to work. To be a working actor in England is a life.

When complicated characters aren't well drawn, they're boring.

There's a new television generation coming in every five or 10 years, and the classic stories stand up to being redone.

There's always a crisis somewhere, and you get the satisfaction of solving the problem. And then, there's always the mystery of whether a program will work or not, and waiting for the reviews or seeing what the audience figures are.

My primary job is to choose the programs, either to co-produce them, or acquire them after they're finished. So, I read a lot of scripts, I meet with producers and I read a lot of books.

Sometimes, the actors are thrilled to have visitors because they're just waiting most of the day. It's the directors that are a little busy.
