That was fast. Yesterday Joseph Gordon-Levitt joined Robert Rodriguez's "Sin City: A Dame To Kill For" and Josh Brolin was said to be one of the additional actors potentially joining the cast. Now Brolin is confirmed. Dimension Films announced today that Brolin has joined the "Sin City" sequel cast as “Dwight," the character that Clive Owen played in the original film for co-directors Rodriguez and Frank Miller. Evidently there's still one more big part up for grabs. The part of the titular “Dame” has yet to be cast.
