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 think people were a little nervous to work with me to start with, because the movies I've done they thought that I wouldn't be able to control myself at all. I'd have to blow up the cars or something like that, and I think also people are scared of working sometimes with feature directors, because they feel like you're not going to listen to their opinions.

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.

I started doing commercials in 2008 right after we released Death Race, and the reason was that I spent two years prepping Death Race and building all these custom rigs to shoot cars in the most dynamic and exciting way.

When that technology becomes widespread and it's on every car on the freeways, it's going to save so many lives. Especially in America, so many people get killed in these multi-car pileups on the freeways.

I think, as a filmmaker, my style of filmmaking is very well-suited to 3-D anyway, so it's not like I'm having to change a huge amount of the way I shoot to work in 3-D. I think you could probably dimensionalize some of my movies and they would make very good 3-D films.

It's all based around the idea that basically VW cars are space age. They're the worst cars to use in action movie, because all the things you want to traditionally do in an action movie they won't allow you to do, because they make you drive safely if you want to or not.
