Sin City 2, aka Sin City: A Dame to Kill For, which began shooting in Austin yesterday, has added Jaime King in a returning role and Jamie Chung (Sucker Punch), who replaces Devon Aoki.  Co-directors Robert Rodriguez and Frank Miller are teaming up once again for the sequel to their 2005 hit adaptation. Their co-written script is a mingling of Miller's comics' storylines as well as a new story written just for the film by Miller.  One plot was taken from the 1993 comic, "A Dame to Kill For," and centers on a man named Dwight and his entanglements with a femme fatale named Ava.  Additional info on casting, such as the possible return of Clive Owen and much more, follows after the jump.

Heat Vision reports

that King will be returning to the Sin City sequel to play Wendy, the twin sister to the angelic prostitute, Goldie.  Mickey Rourke is expected to return as Marv (spoiler: even though Marv was dispatched by electrocution in the first film), since the movie takes place both before and after the events of the original.  Also returning in reprisals are Jessica Alba and Rosario Dawson.  Aoki will not be returning as deadly little Miho, the katana-wielding assassin, but Chung will step into her shoes rollerblades.  The character plays a crucial role in helping Dwight pinpoint the backstabbing Ava.

Here's where it gets interesting.  Clive Owen, who portrayed Dwight the first time around, is reportedly returning to the sequel, but may not play Dwight throughout the entire film.  The character is understood to have undergone facial reconstructive surgery to change his appearance.  So, the search is on for another top-tier talent to play the new Dwight.  Also yet to be cast is someone for Ava's role, one originally written for Angelina Jolie.  Another unfilled role is that of Johnny, a smooth-talking gambler that was newly created for this film.  Looks like there'll be no rest for Rodriguez, who just barely finished wrapping on Machete Kills before hopping onto the Sin City sequel.
