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.

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.

It really has been a blessing because you can go and look at our other movies we've done in a studio system. We didn't get to make the movie that we wanted to make. We made the movie that someone else wanted us to make. That can be a little disheartening, a lot disheartening. While there have been struggles, it doesn't matter which table you're at because you're going to have obstacles, but I kind of like being able to make the movie that you want to make.

It's not like we were forced to do something we didn't want to do. I mean, when you see that scene you'll realize that we're really lucky that the weather came at us because now it has a lot more meaning that wasn't automatically there. There's some sort of undertones that wouldn't have existed had we shot it outside. So we got lucky on that and what we try to do is take whatever obstacles come our way and make them work in our favor.

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 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.

It's a weird partnership. For me and Patrick, if you've met him, we're not very much alike. But we bring such different tools to the table. He doesn't think like me. I don't think like him. He thinks like an editor. He thinks like a director. He thinks completely outside of the box when it comes to writing and so because of that he leads me down roads that I would've never gone down. And he sucks at grammar. So together we're perfect.
