I find it terribly distracting in movies when people do accents, I must say, unless it's terribly serious and the story is rooted in South Africa and you're doing a South African accent. But in period movies I think nothing can be more distracting than people doing accents.

Recently, I've been loving Monster Hunter! A film conversion is currently in planning.

So each of the commercials- basically it's an action movie cliché. "Bus" is very much inspired by Speed obviously, where you have a high-jacked out of control bus, and you have heroes who are trying to jump from a moving vehicle to the bus and they just can't do it because the moving vehicle can't get close enough, because all these VW cars have this distancing technology, which is really fantastic.

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.

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 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.

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.
