no, no1 can say Sin City 2: A Dame To Kill For.
first off, i dont think they would give it a crappy name, i think they would stick with a more suting name like Sin City: Part II, or Sin City: Chapter 2
Also i dont think they would name it after the book, otherwise this would be called Sin City: The Hard Goodbye, The Big Fat Kill and That Yellow Basterd.
And to end off, ive heard they want to do "To Hell and Back" and have Johnny Deep as Wallace, as that was there original plans, and also "A Dame To Kill For".
So whatever they do, it will be good allround, cause this film is the best ive seen in a long time!
