We all wake up in the morning wanting to live our lives the way we know we should. But we usually don't, in small ways. That's what makes a character like Batman so fascinating. He plays out our conflicts on a much larger scale.

The only job that was ever of interest to me other than filmmaking is architecture.

But 'Memento' was so successful, such a huge cult hit, almost on the scale of a large film. If that had happened, with all the acclaim, before the next job, I'd have found it very difficult to figure out what to do next.

I try not to have actors in mind when I write because the tendency then is to be influenced by either their last performance or your favourite of their performances.
