People think, 'Oh, well how can 'The Hobbit,' which is one book, become three films?' But you can take one line from an appendice and it turns into a whole sequence.

I remember kind of doing early acting and thinking, "God, they don't paint behind the sets." It's a bit of a shame, really - "Oh, what's on the other side of this wall? Oh, you can see the plywood." I was really disappointed. I just thought that these things were real, from watching things as a kid.

I suppose the biggest strain was that Hoodwink is a high-octane character and he's up there like all the time. Once he's on his journey there's no let up for the man, so I actually found it a massively exhausting job to keep that level up.

There is always that potential in the same way - Roddy McDowall ended up playing Cornelius to Caesar [in the Planet of the Apes]. Two different characters. That's the joy of the craft. Bring it on I say.

Rather than something like King Kong where I really went after studying gorillas in the wild and captivity. I based Caesar [ from the Rise of the Planet of the Apes] on a real chimpanzee and I worked with Terry [Notary] on a lot of chimpanzee movement.

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.

[Greek] Theater started off and used masks and Kabuki, in the East, they used mask-work. And then, Commedia dell'arte in Italy and then, you know, we're part of an acting tradition and, and performance capture is no different.
