Oscar-winning screenwriter William Monahan has been brought in to give the Sin City 2 script a polish.
Director Robert Rodriguez previously said that financing for the film had been agreed and that Frank Miller's script "could shoot as early as later this year."
According to The Hollywood Reporter , Monahan - who scooped a golden baldy for The Departed 's best adapted screenplay - has now been hired to work on Sin City 2 .
Fansite rumours suggest Mickey Rourke and Jessica Alba could both return in a sequel to the 2005 graphic novel adaptation.
Monahan has been a very busy boy of late. As well as scripting Tom Cruise sci-fi flick Oblivion , he will also reunite with The Departed 's Martin Scorsese to remake The Gambler .
