Stacy Keach (Mike Hammer) has joined the cast as mob boss Wallenquist.
Back in 2009 Frank Miller attended one of Stacy Keach's stage performances of King Lear, and promised Stacy Keach "a powerful role" in Frank Miller's next film.
Jessica Alba said, "In Sin City 2, that one is probably the best experience of my career so far. Working with Robert (Rodriguez) and Frank (Miller) again was inspiring to watch them. They were already so seasoned before they came together for the first Sin City and just to see how they both have grown as artists. Then to see them come together again and how well they work together, its profound what they come up with and what they have done. All their dreams have become fully realized I feel like. When the process is this fun and exciting you know the product is going to be so cool."
Asked if the new story will have a more substantial arc for Nancy Callahan, she replied, "Yes. Yeah, I got to reunite with Bruce (Willis). And in the first one I didn’t get to work with Mickey (Rourke) because he shot his stuff separately, and in this one I got to work with Mickey so it was a dream come true. It was amazing. It was really, really cool."
Bruce Willis said, "I worked a few days on it. It's fantastic working with Jessica Alba and Robert Rodriguez again and his whole crew. I have a confidentiality agreement not to give away the story, but I love working with Robert and I love Austin (Texas)."
