I love Death Race, it's one of my favorite films. I thought, "You know what? All that two years worth of work is now gong to be wasted because I'm highly unlikely to direct another car movie straight away," and I felt at that point there was no one who was kind of better at shooting cars, so I thought rather than let it go to waste I would explore the idea of doing commercials, and that's what I did.

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.

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.

There's something very terrifying about that and very primal about it. It's my belief that what horror does for people is that it provides that primal fear that, when we were wild hunter-gatherers, we had as part of our natural lives because maybe something was trying to hunt and gather you as well. We don't have that anymore in life and that's one of the things that horror films and action films provide for us.

For me, it's a multitude of things. In the modern world, there's a real genuine fear of loss of individuality and I think the undead speak to that. I also think the idea of the dead coming back to life, and this unstoppable foe that just keeps coming and coming, but rather slowly just chases you, is a real primal fear. It's like a fear of claustrophobia, heights or water.

I had this movie, Death Race, that was a passion project for me that I'd had in development for almost ten years.

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.
