“By the time I was 10 or 11, I knew I wanted to make films.” — Christopher Nolan

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.

To be honest, I don't enjoy watching movies much when I'm working. They tend to fall apart on me a bit.

If I could steal someone's dream myself, I'd have to go for one of Orson Welles.

Batman and Superman are very different characters but they're both iconic and elemental. Finding the right story for them both is the key.
