It's difficult to keep anything fresh for an audience these days. With technology being what it is people seem to know everything there is to know about a film before you've even made it.

When you're dealing with the world of dreams, the psyche, and potential of a human mind, there has to be emotional stakes. You have to deal with issues of memory and desire.

Heist movies tend to be a bit superficial, glamorous, and fun. They don't tend to be emotionally engaging.

It's very important that a film that intends to play tricks on the audience... has to play fair with the audience. For me, any time you're going to have a reveal in the film, it's essential that it have been shown to the audience as much as possible. What that means is that some people are going to figure it out very early on. Other people not til the end. Everybody watches the film differently.

When you start really thinking about the potential of the human mind and its ability to create an entire world while you're sleeping, I come away feeling like our minds are not remotely understood by science.

I think there are advantages to different scales of filmmaking. You wouldn't want to do just one thing.

In Hollywood there's a great openness, almost a voracious appetite for new people. In England there's a great suspicion of the new. In cultural terms, that can be a good thing, but when you're trying to break into the film industry, it's definitely a bad thing.
