You don't go - oh this is a motion capture role, I'm going to employ this method of acting. We don't have anything to hide behind when we're doing this.

My first job when I got my equity card was acting in 14 plays back-to-back. Playing that many roles, you look for ways of differentiating the characters physically, which goes hand in hand with understanding them psychologically.

When I was in theater I was forever trying to inhabit a space which puts yourself under the microscope as an actor and your personality and your take on life, but actually through another portal of a character.

The matter is - we are actors playing roles [in Planet Apes] and they happen to be in this instance apes but there's no difference. In the scenes that we're playing, if we were to block out the scenes as actors in costumes, it would be no different.

My sons have to learn that you take the rough with the smooth and they've seen a lot of smooth in the years that they've been around. They didn't see the early years. But both my mum and myself are actors and we constantly tell them it's not easy. But they understand that.

In a personal way, to do with family and the father-son relationship, in a kind of artistic way with regard to him being an art student. I also studied the visual arts at Lancaster University. I then decided to become an actor as he was becoming a musician. And then as an actor/performer, we have similar sort of interests - music hall and that whole world. So, there's a lot that I felt connected with.

I understand why people went nuts for 'The Artist.' We use words so much, it's nice to be able to explore a different way of communication, to be able to express silently what someone - or something - is thinking or feeling.
