Every movie is a commitment of a year or a year and a half. Commercials are much faster than that because they're much more contained. You can get in and out really fast, and you do a piece of work the you see the end result very quickly.

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.

What makes a mockery of a lot of these 3D conversions, where they're shot in 2D and converted to 3D. Having laid a real 3D movie, you realize that it's right in the production design. You design sets that enhance the 3D and you design interactive elements, like the rain or smoke. If you're shooting 2D, you don't know about that.

The way it works in commercials is they come to you with the script and then you do the visual, you do the storyboards, and you give your vision of it, but it's very much their baby. You just kind of put your polish and sheen on it, and you're interpretation of it, but it's very much the agency's idea.

I've so got my plate full with Resident Evil and then The Three Musketeers, I'm just not involved with Castlevania. I'm not personally involved with the movie at all. I'm not producing that. After these two films, then I'm having a holiday.

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.

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.
