Sin City: A Dame to Kill For has added Jaime King and Jamie Chung to its cast, according to Hollywood Reporter.  King will play the role of Wendy, the twin of Goldie, a role she played in the first film.  Chung will take over the role of Miho, played by Devon Aoki in the first film. 

Directors Robert Rodriguez and Frank Miller began shooting the film in Austin this week, slightly ahead of schedule (see "'Sin City 2' Starts Filming in November").

Several important roles are still unfilled, including Ava, Dwight, and newly created character Johnny.

The film is scheduled to release October 4, 2013.
