I love to make movies about young people - young scientists that are inventing things and all the writing they did was very funny and very true.

The studios are never going to make $200 million a picture with those types of movies. It's not familiar to them, and it's not a model that can necessarily be sustained. Now, if they go back to making movies about people ... well, I hope they do that.

In Slumdog Millionaire when you are immersed in the point of view of children in the slum and the bustle of the city, the handheld camerawork is amazing. A handheld camera is perfect for establishing point-of-view and for instilling the feeling that you are there.

I think that the audience should not be able to tell if it is real or not real - it should be an enhanced version of reality, or an artistic view of reality, that captures not only what is physically there, but what is not visible - the mood.

When I do a still picture, I'm doing it all by myself with no help. I'm designing everything. I am my own art director. I'm doing everything. I'm directing, editing, whatever.

The best way to know when there's good lighting is when you don't notice it.

If you use hand-held techniques just to make the film stylish I think it's wrong.
