Well, we studied a lot of books and things like that. Denzel has a personal experience with it, not himself, that's his business-I won't get into that, but he knows a lot about it as well. So, we took some real life experiences that we both-I've been told that I have OCD.

I'm a product of older filmmakers I guess, the past where you get to make movies and scenes are what they are. You know if you think about Scorsese back in the day when he was making Taxi Driver, or Coppola or Frankenheimer, Sidney Lumet, they're making films where you witness violence in a real way.

If you see someone lying out knives and forks consistently, but then one day those knives and forks become weapons you're not sure if he does that as a warrior, that's just his thing.

Sometimes violence in a very real way is much faster and more impactful because it feels real and you're watching it happen and you're watching your star do these things, so it's not like he's doing superhero moves.

You could call it that [urban Western], I guess, you could certainly call it that. A lot of these types of films are, really, if you get down to the core most suspense thrillers in this genre, the Western is sort of the birth of it all.

Some men don't gel when it comes to work - you have different work ethics, different opinions, different points of views, different methods of filmmaking - and we didn't gel.

I don't think I've seen that sort of character in a long time in this genre because again, there was a time when you could have quirky, strange characters that you grew to love, you didn't quite understand, you know, and then all of a sudden they became almost cardboard cutouts for awhile. You kind of know the guy, what his deal is - this guy's hard to figure out. He has some strange habits, but, you learn to love him and you discover more about him, where it comes from.
