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 was excited about the fourth movie I guess conceptually because, what I felt we should do it, we should try to make it a conceptual jump like Terminator did to T2. It was still the Terminator franchise, but it was something kind of bigger and grander.

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.

When that technology becomes widespread and it's on every car on the freeways, it's going to save so many lives. Especially in America, so many people get killed in these multi-car pileups on the freeways.

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.

I went for a more classical approach to filmmaking with lots of dolly, track and cranes, and slightly slower, more choreographed fight moves, so you get more fight moves in one take.

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.
