There is a difference between creating something and just capturing something. And when we were using film, it was not that fast, and it was expensive, so there was incentive to make sure the shot was exactly right before we rolled. With digital, it's fast and its cheap, and it's easy to bypass the rest.

I love Woody Allen. He's very clever, always thinking, and he's great with actors. He lets actors do what they want to do and occasionally he'll give them a specific kind of direction.

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.

If you need to strap a camera to you or get in a small space, then it makes sense to use digital.I do think it is possible to use a digital camera artistically, but it can only be good if you are using film technique. Film has grain, and digital has pixels, and there is not that much of a difference, but digital does not replace the need to create a scene and light it properly and spend time considering the shot.

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.

There are a lot of directors out there that don't like to deal with actors, I think. Many of them have said something like, in the future they will actually manipulate the actors on their computers. But don't believe all this.

I shot a lot of commercials and sometimes I enjoy the commercial shooting and sometimes I really hate it, but in thirty seconds or one minute, you can make some remarkable work shooting in one or two or three days.
