We played more rock music when we were writing the script. 'Renegade'. All of the Styx songs. All of the old '70's and '80's music, that's the stuff that's pounding in the background while we were doing this stuff. It's a part of those movies.

I mean if you look at the Charger and you compare it to other cars, the way the lines work, the tires, in 3-D it's gorgeous. One thing that we found was that the reflective surface was weird. It does funny things in 3-D. So you have to deal with that.

'Scissorman' is terrifying. The studio at the time didn't want Scissorman because they were afraid that he'd look silly to which my response was, 'Well, then why did buy this because that's what the game is.' But I lost that battle.

I mean, 3-D adds a whole level of 'oh my goodness' to the movie in good ways and bad ways that you have to deal with. We've overcome any obstacle that we've ever had because we have a great 3-D crew, Max and the guys at Paradise 3-D.

There is a shortage of hard R. It was the story and the character. He's never played a character like this and so that was the thing that really won him over. The story itself, on the surface - Patrick and I love actors almost in a geeky kind of way.

It's funny, if you go back and look at all those old movies a lot of times they didn't have the budget for music. Each scene here was written to a different time, whether that be 'Breakfast in America' or just different soundtracks that we had for different parts of the movie. I'm interested to see how it all plays once it's all put together.

It's modern day. It is modern day. Some of the cars are older but it is absolutely modern day. There are modern cars in it, modern people, modern clothes, modern talk. We wrote 'Valentine' to sort of pay tribute to all the old slasher movies that we grew up with and I think that we did that.

We really did it write it for the story but once you get into production, once you start doing this process certain things will jump out at you. Some shots will be more 3-D than others.

I love the 3-D. I'm not one of those guys who's scared to death of it and think that it's going to take over everything. I love the fact that you have the immersive 3-D and the voyeuristic 3-D and then you have the in your face gimmicky 3-D and we're going to do both. I think there's a place for both.

Just like in any other movie, too, we've had car troubles. We've had issues with weather. We've had issues with you name it. You can't predict this tough but as long as you go at it with the mindset that it doesn't matter what happens, we'll just figure out a way around it - that's the reason that I'm here.

I think that's coming just like anything else. I don't think that it's just going to be 3-D. I think that 2-D is going to be around forever. I think that we'll go back and forth.

As long as we work within the budget and are responsible, which by the way it's amazing how many people aren't but we are. We've worked within the budget. We've worked within the time and we're making the movie that we want. That's the reward and I couldn't be happier.
