but, i think i might change my mind. check out these quotes from an article here.
"The bulk of the movie will be black-and-white, like the graphic novels, but spots of color will show up here and there, again just like Miller’s comics: a red dress, crimson lipstick, the Yellow Bastard, etc. Filming in color and then processing the film into black-and-white makes this possible. Some other interesting effects will include white silhouettes and even white blood against a black background. When Rodriguez says he’s sticking to the books, he means it.
Perhaps the most amazing quality about the Sin City movie is that Rodriguez and Miller are capturing the graphic stories shot-by-shot and frame-by-frame, using the graphic novels themselves as storyboards, reference sheets, and scripts all in one. Miller’s exact dialogue will be the dialogue in the movie, and the angles, backgrounds, and lighting are all coming directly from the comic pages.
Superstar director Quentin Tarantino is directing a crucial scene in the movie. One can only assume it’s the big slaughter scene that is the climax of The Big Fat Kill. In order to accommodate Miller and Tarantino as co-directors, Rodriguez had to resign from the Director’s Guild of America. At the panel, he didn’t seem too worried about this, since Tarantino isn’t a member of the DGA either."
and, for the dvd,
"While the movie will be divided into chapters, each representing a different graphic novel, all the stories’ timelines overlap, as they do in the books themselves. However, on the planned DVD version of the Sin City, each chapter will be its own individual menu feature, so viewers can watch each story separately, or watch them together as they will be in the theater version. For the individual chapter versions, extra footage will be included, since not every piece of footage will fit into a two-hour movie, said Rodriguez."
sounds interesting, doesn't it?
there are some images of the film posters at the link, if you're curious. didn't feel like linking them.
