For me, time is the greatest mystery of all. The fact is that we're dreaming all the time. That's what really gets me. We have a fathomless lake of unconsciousness just beneath our skulls.

I read a lot, that's my main hobby. I've got an iPad which I store books on and I read voraciously. I'm a slow reader but I'm obsessive. I make references, underline things, cross-reference. I'm an autodidact.

I don't have any expectations about my films. If they're good, they're good - if they're not, they're not. About 10 years ago, I remember going to see one of my movies - I can't even remember which one now - and everyone was jumping up and down, getting excited, saying what a great film it was going to be. We all went in and watched it, and it was the slowest movie I've ever seen. The next day, the reviews were terrible and half the studio was fired.

By giving up 'the need' and 'the want', things begin to happen for you

I wanted revenge; I wanted to dance on the graves of a few people who made me unhappy. It's a pretty infantile way to go through life - I'll show them - but I've done it, and I've got more than I ever dreamed of.

I wouldn't use the word 'scared' for my role as Hitchcock, but it was my most insecure. Taking on such a formidable, giant personality such as Hitchcock; he was one of the great geniuses of world cinema. Sheer genius.

I think doubt is a very healthy way to live.
