I'd seen too many shrines in South Central and thought it was worth asking where the first bullet came from that started all this violence.

There are many stories of people didn't set out to make a film that became a classic - the whole process was a disaster, everybody hated each other, the movie itself was a disaster, everybody thought the movie and the script was going to be a piece of crap. Look at Alfred Hitchcock and Psycho. Nobody wanted to make Psycho; it was crap to them. The only person that wanted to make Psycho was Hitchcock. Now, it's considered a classic and a work of art.

I like being in real environments. I love being in the place that it's about - these sets and locations are characters in the movies. Can you imagine Breakfast at Tiffany's shot somewhere else? It's classic. Characters are part of storytelling; they're just as important as everything else.

In movies you get to do that. Sometimes with the vigilante justice movie he has to also tangle with police, which are traditional or security people. Is there going to be any of that in this?

Movies are so hard to get made - every step of the way of making a movie has obstacles. If you don't have that passion, if you don't have that vision, if you don't believe it's a piece of art worth making, then you probably won't get it made - you won't have a chance for it to be something special.

Not harder than it should be, no. We're about the business, we're about the work. It's all about the work, always. We have fun and laugh and there're days that are more intense than others, but we're there to make it better. He's always going to try and make it better, I'm always going to try and make it better. So you accept anything, you accept whatever it takes to get it up on the screen and make it worthy.

I became a director just for the love of movies, because of the power of cinema.
