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.

You have to offer sort of an evolution visually and do things like you've never seen before, like a fight between two men in a toilet on an airplane which was very exciting.

For me, it was the challenge of doing a movie that is in one location. Usually, there are a few scripts obviously always going around with stories that happen in one location.

Producers and studios want to make movies that are more appealing internationally and I think that you have to use your different cultures as an advantage to be able to make those movies.

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

It's hard to do a camera inside of a car. Non-Stop would have been impossible. Usually modern lenses you can focus up to the lens pretty much, but anamorphic you can't. You need like three feet.

Anamorphic doesn't really lend itself to the big shots.
