One of the things you do as a writer and as a filmmaker is grasp for resonant symbols and imagery without necessarily fully understanding it yourself.

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.

Whether it's Baidu or Chinese versions of YouTube or Sina or Sohu, Chinese Internet sites are getting daily directives from the government telling them what kinds of content they cannot allow on their site and what they need to delete.

Einstein had looked at the numbers and dimensions that went into his equations for gravitational waves and said, essentially, 'This is so tiny that it will never have any influence on anything, and nobody can measure it.' And when you think about the times and the technology in 1916, he was probably right.

Looking down the road, space exploration and the benefits it yields - in medicine and information technology - should not be overlooked.
