You really feel like you're on the cutting edge and you know you are because all the camera equipment you take for granted doesn't exist for 3-D. So all the cranes with all the stabilized heads, they don't work on 3-D because they're all built for lightweight camera packages. As soon as you kind of put two cameras together and all the other crap that they need and the cabling to go back to the computers, we've literally, the cranes on these movies, they break after a couple of days.

I really believe in 3-D. I really think it is the wave of the future for cinema.

My approach has always been to put 100% into the movie I'm making right now. I think sometimes filmmakers put too much thought into the grand franchise they're going to build. And guess what? If the first movie doesn't work there is no franchise, so I'm always concentrated on making the best, best possible movie right now.

The cameras were a little twitchy, and you'd get less footage and less set-ups every day. The interesting thing about it was that you just composed images in a completely different way because we had big 3D monitors on set, and you'd wear the glasses and see the image in 3D.

Death Race was a very modern action movie and it used all of those modern action techniques with lots of hand-held camera, lots of punchy zooms, and lots of quick movements and quick cuts. In 3D, I didn't want to do that anymore.

When you're writing it's a very solitary job. It's you and your word processor and a cup of tea. It's nice- that again, is another nice thing about being able to do commercials is, you can get out of the house and chase high speed cars around for a few days and then by the time you go back, you're kind of re-infused to write.

I was excited about the fourth movie I guess conceptually because, what I felt we should do it, we should try to make it a conceptual jump like Terminator did to T2. It was still the Terminator franchise, but it was something kind of bigger and grander.
