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 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 really believe in 3-D. I really think it is the wave of the future for cinema.

The idea of doing a period movie, some people say, "Isn't it odd that you're doing a period movie? That's a change of pace for you." And, I'm like, "Not really." When you're doing a science fiction movie, it's almost exactly the same.

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.

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.

The other video game adaptation I did was Mortal Kombat, and I did that because I loved playing the games in the arcade. I play all of the Resident Evil games because I'm very much immersed in that world.
