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.

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 would've never done a 1970's road movie. It just wouldn't have occurred to me. So when he started talking about it he brought up all these movies and he'll do that with you guys and you'll feel the Goosebumps as you start realizing the story that he wanted to tell.

So we have that, where there are moments where it's just Nic Cage and Amber Heard and you're in the car with them and it's not stuff flying at your face but you're literally sitting in the backseat. You're sitting there and it's just sort of interesting. At the same time we're going to throw cars and guns and bullets and frogs and naked people at your face because it's fun and that's the roller coaster. We do write some things for 3-D.

'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 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.

It's a road movie [Valentine]. I mean, yes. We film it here and it takes place from basically Colorado to Louisiana. That's the road trip. So we're all over the place. We go through bits of Texas and bits of Oklahoma.
