The actors come in and they make characters their own and so Patrick and I have never been the kind to think that our script is the bible. We want to make sure that the story is told, that you stick to the story but if you have to make changes to the character then that's fine. A lot of times there are some funny one-liners, funny things that happen that are out of the ordinary. I like it.

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.

This as hard an R as we wrote in the beginning. It was fast. It was fast mainly because of De Luca. We came in with De Luca. Nic I think had a deal with Millennium and so we ended up with Millennium quickly and they said, 'Go make the movie that you want to make. Basically, here are the ground rules; stay within the budget, stay within the time and go make your movie.'

I think it's just as viable a way of telling a story as anything else but for right now we like playing around with the new ways to do 3-D because I think it's only going to get better. I think that eventually we'll come home, we'll sit in our living room and there will be a little hologram that'll pop up and you'll watch these 3-D movies but you'll be able to walk around it.

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.

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.

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.
