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.

These days that wouldn't happen - waiting for the light to be exactly right. Because it takes time and time is money. And with these big productions with expensive actors, you just don't have the time to get every shot exactly right.

When I first came to America there still was Look Magazine and LIFE Magazine, and the photography in those magazines was amazing to look at. They had the best portraits, and their news photography.

There are, of course, many, many, many good cinematographers and unfortunately they don't work as much as many of those people who do those crazy, stupid movies.

Kubrick was one of those directors who actually did practically everything in his movies. He actually directed, photographed, wrote, lit, edited - everything. A few people can be like that.

Using film was so much easier than the digital technology of today. But digital is still at the beginning of what it can be and they'll be fixing all those problems. It's just too complicated - negatives, tinting, flashing - it's a whole new system that takes a lot of time. Of course, it's not as physical. Even the editing. You used to feed a piece of celluloid into an editor. [Digital] is not expensive and that is an advantage, but I must say that I don't love it.

I was really fortunate from the time I arrived in Hollywood to work with some of the greatest directors from the beginning. I worked with Robert Altman, John Boorman, and of course Steven Spielberg, Michael Cimino, Brian De Palma ... I couldn't pick one of them; they were all different, but they are all so talented.
