The power of sound to put an audience in a certain psychological state is vastly undervalued. And the more you know about music and harmony, the more you can do with that.

In discussing the process with the actors, I made it clear to them that they could improvise but that the sum total of their improvisation needed to impart certain plot points, and schematic material.

It's difficult working with very rich actors, because inevitably they become a little spoilt, and the managers and agents tend to control things more than is healthy.

I play piano and trumpet. I studied classical guitar.

One of the things I love about cinema is the range.

I am intrigued enough to want to continue, and also to try and work with companies like Sony on modifying the cameras and making them more user-friendly and efficient.

But I don't have such a strong desire to need to get away from filmmaking.
