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

I like alternating commercials with movies, because it keeps the pace up. You can't slack on a commercial. You need to go fast. That's a terrific piece of action, I think if that was scheduled for a movie, you'd put that in for two or three days worth of work.

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.

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.

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.

Commercials are also any opportunity to meet new crew and work with new kind of rigs. You can explore working with different people without having to make the full commitment of having to do an entire feature film with them and see whether you like them. Also it's great for testing out new equipment, like on the last spot we just did, I used a lot of drone technology, really cutting edge drone stuff, more than I've ever done before, and it worked out really really well.

I'm very impressed and the next movie I do I'm definitely going to use a lot of drones in it, because they're very light and flexible and fast, and there are things that you can do with them that you can't possibly do with a helicopter for safety reasons.
