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

It's a different rhythm than most movies. For a lot of the actors, you're 12,000 miles away from home. It becomes a way of life - getting up at five in the morning, shooting every day, day in day out, for 270 days. The new cast playing the dwarves were carrying incredibly heavy weights in their suits, they sat through hours of make-up every day. So it's quite challenging from a stamina point of view.

What I'm saying is people like Hoodwink are not kind of evil villains, they're part of humanity. We can choose to disassociate ourselves from them and we can choose to pretend they're not there, but they are. We're all together in this.

'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.

When you have children, you realize that at the end it's all about passing on, about handing down. The process of letting go, not attachment, but appreciating the beauty and value in the change, the transformation.

At the moment, my trajectory isn't to think about acting. I'm absolutely devoted to The Imaginarium, our projects and directing. And watching and enabling other actors do their thing in our studio is hugely rewarding. I expect at some point I'll probably want to go back on stage and do some theater, because I've not done theater in 10 years.

I can get on with all different sorts of people, and I never feel homesick, particularly, or I've never felt kind of patriotic towards any one country.
