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.

If you do any thriller or horror movie a big part of the process is accounting for the cell phone.

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.

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.

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

I think it's very interesting for a director that enjoys thrillers and mysteries like I do to have the challenge to do that.

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.
