It's a very different experience shooting in 3-D because the camera rigs are so large. Everything we've become accustomed to in the last ten years as filmmakers, which is cameras getting smaller and smaller and you can just throw them on your shoulder and stick them in a car and do whatever you want, you can't do any of that now. You're forced to put things on dollies and track and cranes.

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 think people were a little nervous to work with me to start with, because the movies I've done they thought that I wouldn't be able to control myself at all. I'd have to blow up the cars or something like that, and I think also people are scared of working sometimes with feature directors, because they feel like you're not going to listen to their opinions.

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.

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.

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.

One of the reasons why Resident Evil is a very successful video game franchise, much more so than a lot of others that have fallen by the wayside, is that they have constantly evolved.
