Sin City (2005) is no ordinary comic book movie. Nor is it your average book to screen movie adaptation generally. Director Robert Rodriguez personally sought out author Frank Miller, creator of the original Sin City graphic novels, to co-direct the movie with him. With the author not just on set, but also directing, what you end up with is essentially the most faithful movie adaptation possible. Today I'll look at how Robert Rodriguez convinced Frank Miller to make the movie, and what the implications of that were. Next time I'll complete the story by discussing the technology behind turning the Sin City novels, visually, into a feature length film.
