"Sin City" scribe and co-director Frank Miller has revealed to Now Playing Magazine that he and director Robert Rodriguez are "working on the final touches of how the story [for Sin City 2] is going to work, and we're right now planning to start shooting in January."

While this may seem like an accelerated timetable, the push can be attributed to the first film's box office success as well as Rodriguez's inability to remain idle. "Robert doesn't mess around - he gets right to it," Miller explains. It's unknown at this time whether Miller will make another cameo in the new movie - in the first, he played a priest murdered by Mickey Rourke's Marv character.

Miller also notes that the plot for the second film will come from his acclaimed Sin City graphic novel A Dame To Kill For, "plus a new story that I've created for [the movie] that weaves in and out of the larger story." This should comfort fans who are worried that the film franchise will end when the previously-published material runs out. As Miller puts it, "I don't really plan on running out of [material] 'cause I'm still doing [the comics]. ... There's material in my head that could go on forever."
