Sin City 2
It looks like there is talk about a Sin City sequel:
“Frank Miller, who wrote and co-directed Sin City based on his graphic novels of the same name, told SCI FI Wire that he plans to co-direct the upcoming sequel, Sin City 2, with Robert Rodriguez, despite rumors to the contrary. “Yes and yes,” he said in an interview following a preview screening of footage of 300, another upcoming film based on his work.
“We have all kinds of technical things we want to do, but there’s a major story called A Dame to Kill for [which was, fittingly, the second Sin City story and is a prequel of sorts to The Hard Goodbye] that we’re going to adapt,” Miller said. “That’ll include a new femme fatale and other characters.” Rodriguez has reportedly spoken with Angelina Jolie about playing Ava, ex-lover of Clive Owen’s Dwight.”
