What you can do with visual effects is enhance the look of the character, but the actual integrity of the emotional performance and the way the character's facial expressions work, that is what is going to be created on the day with other actors and the director.

I think what traditional studios probably don't understand is that it's a genuine advancement in the actor's tradition. And you know, the tradition and craft of acting. And it's the latest step. You know, we, we tend to find forms of delivering stories that fit our times.

That's why I ended up going to Lancaster University, because they had a visual arts course, and in the first year it was like a broad visual arts course in sculpture, painting, graphics - all of that.

Motion capture is exactly what it says: it's physical moves, whereas performance capture is the entire performance - including your facial performance. If you're doing, say, martial arts for a video game, that is motion capture. This is basically another way of recording an actor's performance: audio, facial and physical.

I'd already started directing short films when we were doing 'Lord of the Rings,' then videogame projects. So Peter's known that I've been heading towards directing for a long time. But I always thought my first outing would be a couple of people and a digital camera in the back streets of London somewhere!

You're watching your kids playing football and you're not present. It's like the worst... it's horrible. I despise myself for it. I think it's a particularly male thing. Being present and in the moment with your kids is something a lot of men struggle with.

I do listen to myself sometimes and think, 'Is my moral compass so easily swayed by the characters I play, or is it me growing as a human being?'
