HollywoodReporter says that things might be moving forward after all on Robert Rodriguez's Sin City 2. Screenwriter William Monahan (Departed, Kingdom of Heaven) has been hired to make a contribution to the film's script which had been originally completed by Frank Miller himself. Robert during press for Spy Kids 4 revealed that the sequel could start shooting as early as the fall. I'm still hesitant for more Sin City films now that six years has past and the high quality of the original. It's hard to believe it could be improved upon or even be as good.
