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.

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.

In a way it was a modern story but it played to all those 1980 slasher movies. We did the same thing with this. Patrick wanted to do a 1970's road movie and if you'll see, this is a modern story but it's got so much 1970's in your face feel to it. So that was the point, to take that stuff that we loved growing up and sort of do it for today. I think we accomplished it. We'll see.

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.

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.

That's where the inspiration was and so the more that you rewrite and the more you rewrite and the more the numbnuts are coming in to give you notes then the more problems you run into and the more it suddenly doesn't seem like the movie, the story, the characters changed, watered down and we don't have that with this.

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.
