The cameras were a little twitchy, and you'd get less footage and less set-ups every day. The interesting thing about it was that you just composed images in a completely different way because we had big 3D monitors on set, and you'd wear the glasses and see the image in 3D.

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.

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.

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.

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.

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.

What happened with Final Destination was that the movie was in post-production for a long time and I think they changed a lot of the deaths, so a lot of those things were last-minute additions. Everything we shot is in the movie and it's all been designed. We didn't change anything. It's been a year of making those things happen, exactly as we had pictured them.
