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.

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.

There was a lot of pressure on me as a filmmaker to raise the bar and do better than before so, you know, I put a lot of thought and energy, that's for sure.

Every movie is a commitment of a year or a year and a half. Commercials are much faster than that because they're much more contained. You can get in and out really fast, and you do a piece of work the you see the end result very quickly.

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.

I think 3-D across the board both in a home format and cinema is, it's going to be very big.

I think, as a filmmaker, my style of filmmaking is very well-suited to 3-D anyway, so it's not like I'm having to change a huge amount of the way I shoot to work in 3-D. I think you could probably dimensionalize some of my movies and they would make very good 3-D films.
