I read everything that Tolkien wrote, and also read biographies of him. I was fascinated by his experiences in World War I, which includes the loss of life of some of his very, very close friends. I think he writes about that a lot in 'The Hobbit' and 'The Lord of the Rings.'
I try to keep at a non-obsessive level of fitness. It's not about looking great, it's about just feeling good. So I do a lot of yoga. Bikram just blows my mind. It's mental as well as physical; if I don't train, I get very depressed.
Trying to please everyone can be very hard, but, like 'Shrek' or 'The Simpsons,' 'Robin Hood' manages to entertain adults and children at the same time, but in different ways.
