Las Vegas is a 24-hour city. It never stops.

I've always been a fan of 3D, going back to movies in the '50s. I was part of the early '80s 3D craze, which was coming at you in Jaws 3D, so I've always wanted to make a 3D film.

I think that horror films have a very direct relationship to the time in which they're made. The films that really strike a film with the public are very often reflecting something that everyone, consciously or unconsciously feeling - atomic age, post 9-11, post Iraq war; it's hard to predict what people are going to be afraid of.

All the copycat movies were always PG-13 and people said: "Nobody wants violence."

I'll direct any movie starring a monkey or the Olsen Twins. Preferably both.

Movie stars need to retain some of that mystique if you are a big movie star.

You have to write scenes and design scenes that are scary and horrific, but that are also watchable. I didn't want people to just feel like they got punched in the stomach.
