You have to think of each stage of the movie and how it progresses, get into the state of mind of the character, and then match the camera to that, and keep making it tighter and tighter and crazier and crazier so people don't get bored. You know you cannot do a similar shot that you did at the beginning of the movie at the end.

I wanted to move away from the disaster airplane movies that we have seen in the past and do something that was more mysterious, and delay until the end the resolution of the mystery, and then have to deal with the plane itself.

Camera's are cheap. It's the lenses that are expensive.

The hard part on the subway is that you have, let's say, eight hours, but you have to hit these deadlines. From here to here, you can use this part. From this time to this time, you can use that part, and you have to hit them and it gets very stressful.

Anamorphic is very difficult because the distance from the lens to the person to focus is very long so you need a lot of distance from the camera to the person so that means that you need a lot of space.

I think video is very useful, but it's very useful when you want a certain reality.

I think that everything changes when it goes through the Mac; it's cheap. I think people then don't pay too much importance to the take, if you can do 40 takes.
