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

Now that everyone's shooting digital they want the anamorphic to soften the look. You know, to make it more filmic.

I will shoot on film as long as they make it.

These days in movies you can always come back to a location or do an insert or do something, so that's not even an issue any more. But coming back every day to the same plane, it messes with your head.

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.

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.
