Frank Miller's Sin City, great comic, really viberant. Black and white with hits of colors when needed. Pick up the comics, read the hell out of them, love them, in fact if you can find a way, make glorious love to it. After that, on April 1st 2005, go see Frank Miller's Sin City in theaters.
Download, watch it, love it. It is the theater version of the trailor, in fact if I can find it I will put up the 8 minute long teaser for it.
