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.

Interestingly it's when you come to the comedy, that's where a lot of the discussion is. It's like ten people sitting around talking about what is funny. "Is that funny? Is that funnier than that? Is this slightly funnier than this?" I guess that's what it's like when you're making a comedy movie as well, you just have to sit around talking seriously about the nature of comedy.

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.

3D is very exciting. I love it. I'm a complete convert. Everything for me, from now on, is 3D. I'm completely convinced it's the future of home entertainment, as well as cinema entertainment. I think it's a paradigm shift, in terms of cinema, and those things don't happen very often. The introduction of sound, the introduction of color photography and now 3D have been the big shifts. They happen once every 40 or 50 years, so it's very exciting to be a filmmaker, working while one of them is happening.

When we wrapped Resident Evil, we were a 3D movie, but it was no big deal. And then, Avatar came out and the whole of Hollywood was like, "Look at these grosses! 3D is huge. Let's all be 3D!" We just got on with doing what we were doing, which was making what we think is a really quality, kick-ass 3D movie, and we'll really be the first live-action 3D movie of the year.

If you work with any new technology, you have to expect that it's going to be a little problematic.
