Not to be confused with John Woo's Hard Boiled, based on the ultra-violent comic book created by Miller and Geof Darrow. Unlike Sin City the artwork wasn't done by Frank and it is brightly colourful. Darrow's style has a very "Heavy Metal" feel to it with a bit of "Blade Runner". Yet the film noir feel is still apparent in the story and dialog. It looks like Frank Miller is in talks to direct. Miller talked to MTV during the New York Comic Con about the project. At one time it was developed as a starring vehicle for Nicolas Cage with none other than David Fincher directing.
Originally published in 1990 by Dark Horse Comics and drawn by Geoff Darrow, “Hard Boiled”. Winner of the coveted Eisner Award! Carl Seltz is a suburban insurance investigator, a loving husband, and devoted father. Nixon is a berserk, homicidal tax collector racking up mind-boggling body counts in a diseased urban slaughterhouse. Unit Four is the ultimate robot killing machine -- and the last hope of the future's enslaved mechanical servants. And they're all the same psychotic entity.
I could see Bruce Willis as Nixon.
Although Sam Worthington (Avatar, Terminator Salvation) and Clive Owen (Children of Men, Sin City) could easily fit into the role as well.
Frank Miller's The Spirit success will be very important if he wants to be able to helm. If it doesn't do well I could see a few directors that could do it justice. Luc Besson, Robert Rodriguez or Zack Snyder would be able to bring this futuristic vision of L.A. to life.
Here are a few more panels from the graphic novel. They are great examples of the scale that should be in mind.
