According to Heat Vision, Monahan will be supplementing a previous draft by Miller himself. The first film was an assiduously direct adaptation of several stories from Miller's comics, and as such most of the heavy lifting on the script consisted of working out a coherent, Pulp Fiction-style structure, putting all those stories together satisfyingly. The sequel, though, contains at least one all-new segment set in Basin City, called The Long Bad Night.
At San Diego Comic-Con in July, Rodriguez explained that financing for Sin City 2 is in place and that production could very get underway this year. "If it's going to happen, it's going to happen this year," he told the Hall H crowd. While not exactly a guarantee, it's at least pretty confident.
He also confirmed yet again that the story will contain the new segment as well as one based on A Dame to Kill For, which tells a story featuring Dwight, the character played by Clive Owen in Sin City. When news of a potential sequel first came up years ago, Angelina Jolie was repeatedly mentioned as a possibility to play said duplicitous dame, but given the amount of time that's passed, that may no longer be in the cards.
Apparently, Rodriguez believes that most, if not all, the surviving characters from the first film will be back for a second round, should one actually become a reality. The green-screen production, based in Austin, makes it easy to lure a cast of busy, high profile actors, since they can complete their parts in just days and don't actually have to shoot scenes together. Mickey Rourke and Elijah Wood shared multiple scenes in Sin City, for example, but neither actor was on set at the same time at all.
Monahan made his feature screenwriting debut in 2005 with Ridley Scott's Crusades epic Kingdom of Heaven. The next year, he won a Best Adapted Screenplay Academy Award for The Departed, and he'll once again work with Martin Scorsese and Leonardo DiCaprio on a remake of The Gambler. He recently contributed drafts to Joseph Kosinski's science fiction film Horizons, to star Tom Cruise, and his directorial debut, London Boulevard, will be available via VOD on October 5th.
So, will Sin City 2 actually happen, or is this a pipe dream, even with a heavy-hitting screenwriter helping out?
