The whole chameleon thing about acting. That's why I'm moving towards directing - it's a much more healthy occupation.

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 belief about performance capture is that it's a technology which allows actors to play extraordinary characters. But from an acting perspective, I've never drawn a distinction between playing a conventional, live action character and playing a role in a performance capture suit. And from a purely acting point-of-view, I don't believe there should be a special Oscar category because I think it sort of muddies the waters in a way.

35mm film isn't ticking away so it's subconscious - performances are allowed to breathe in a much more real way I think.

In 'Tintin,' it's like a live-action role. You're living and breathing and making decisions for that character from page 1 to page 120, the whole emotional arc. In an animated movie, it's a committee decision. There are 50 people creating that character. You're responsible for a small part.

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.

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.
