The reality of any location in Britain being used in a TV program of a film is that something bad is going to happen! That's the nature of drama. Most of the things that get made or basically grisly detective shows about murders, accidents or medical dramas.

I think CGI is interesting but it's too expensive and limiting in terms of what you can do shot-by-shot.

Film is more of a dream when you're younger. I found it almost impossible to see how you would get into the industry having no connections, nobody in the family being anywhere near it and never meeting anybody that had been on a set.

Sometimes my scripts get so dissolved, and they're so different from when I wrote them originally, that I find it hard to find what I wrote in it.

I think a big part of my job is to make an atmosphere on set and have an attitude that it's about experimentation, and you can't do anything wrong. It's not about judgment, it's not about me kicking over a chair and storming onto set and acting stuff out and telling people to copy what I do. That is a style of directing some people have, but I don't understand it.

Society is about masks and hiding and pretending to be something that you're not and not opening up, and in acting, you do all of those things, but it also shows the performers in a very raw state. They have to literally upset themselves to get to that position sometimes. You don't need a load of people judging you or not being interested in what you're doing or being an ass on set because it ruins it.

Doctor Who is pretty dark, I think. Generally its dark; its always been dark.
