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.

So it's hard to be an artist and be true to the reality of the world you want to create and also make it entertaining and successful financially.

OCD, we discovered is a lot of different things-it's not just washing your hands, it's whatever you're obsessed with. It can be just the way you hold a pen, and you always have to have it a certain way or you have to eat your food, it depends. It's something that, as a character I thought was really interesting because sometimes it's used in a film where it is OCD and sometimes it's strategic.

I don't think the audience goes and thinks of the movie as a piece of art - there are some independent people who may go and have a higher appreciation for filmmaking. It is a great art form, but I don't think you look at a painting and a movie with the same eye.

The violence you witness is Denzel doing it and we're taking some visual effects and doing some things and you see something happen it's happening in front of you as opposed to cutting away and doing a bunch of tricks. It's in front of you. So it's hard not to make it a hard "R" if you see a guy get punched and teeth wind up in someone's knuckles.

I think people go to the movies to be entertained, to have an experience, to disappear from their own reality for a couple of hours. If the film truly succeeds in everything the filmmaker sets out for it to be, then it's elevated to art. It's elevated to something special, because it gives people a visceral feeling of something they're experiencing as a collective group. You feel something and that's what turns it into what you may call art.

My experience of test screenings is that you don't know what kind of mood people are going to be in, and sometimes the studios accept what Joe Blo says - and this guy could just be a frustrated filmmaker, or not paying attention.
