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'm a very collaborative person, so that's not the way I work any way. Once VW got over the idea that I was going to blow their cars up, then we shot the thing really fast and it came out really good. Like I said, it won a bunch of awards and that really was the start of working in commercials.

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.

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.

3D really altered the way I shot the movie completely, and it was exciting because, after 20 years of filmmaking, I felt like I was making my first movie, all over again.
