I think even back as far as 'Lord of the Rings,' there was always the chance that 'The Hobbit' would be made, even way back then. Of course at that point, Peter Jackson didn't probably think at that point that he'd be directing it.

I think there will always be a particular generation of actors who... think that they're going to be replaced by robots. But certainly the emerging actors... understand that that's part of the craft.

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.

I'm in the early stages of a film called 'Freezing Time' about Eadweard Muybridge, the Victorian photographer who was really the forefather of cinema. Digital animators still treat his images like the Bible. He was a very obsessed man.

I'm quite contrary. If people agree on something, I tend to gravitate the other way by my nature. I don't like to be told what to do. I think it goes back to school. I like to do things I want to do and I really don't like doing what I don't want to do.

I've always thought of acting as a tool to change society. I watch a lot of actors and I see panic in their eyes because they don't know why they act and I know why I act. Whether I'm a good or a bad actor, I know why I do it.

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 the same way 'Lord of the Rings' was an interpretation of the book, 'The Hobbit' is being treated the same way. It will be faithfully represented with a fresh interpretation.

More and more good actors are now transmigrating into the videogame space and playing roles there because it's where my generation of kids get stories from.

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.

My dad was working abroad, in Iraq, and he was a doctor. We used to go and visit him, in Baghdad, off and on. For the first ten years of my life, we used to go backwards and forwards to Baghdad, so that was quite amazing. I spent a lot of time traveling around the Middle East.

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.

My take is that acting is acting. A performance is a performance. With performance capture, if you don't get the performance on the day, you can't enhance the performance.

Not a day goes by where I'm not reminded of Gollum by some person in the street who asks me to do his voice or wants to talk to me about him. But because 'The Hobbit' has been talked about as a project for many years, I knew that at some point I'd have to reengage with him.

Originally when I went off to work on 'The Lord of The Rings' I got a call from my agent saying that I was just going to do a voice. But I couldn't really approach it like that. To get Gollum's voice I had to play the character.

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.

The fact of the matter is that an actor, if I'm playing a performance capture role and you're playing a live action role and we're having a scene together, there's no difference in our acting processes.

'The Hobbit' was one of the first biggish books I ever read. I remember vividly the 'riddles in the dark' passage, and it meant a lot to me to finally get to play it after all these years.

The wonderful thing about 48 fps is the integration of live action and CG elements; that is something I learned from 'The Hobbit.' We are so used to 24 fps and the romance of celluloid... but at 48 fps, you cannot deny the existence of these CG creations in the same time frame and space and environment as the live action.

We've never had nannies. We've had great grandparents, great support from family, and the kids have been on every set: they've seen me play Gollum, King Kong, Captain Haddock, the lot. They totally get it, and they want to go into the business. Ruby, my daughter, is very keen to become an actress.
