So we're now familiar with the style and effects so there has to be a bigger focus on the story this time to make Sin City 2 as much of a success as the first movie. It better beware relying on the style though, Matrix showed that doesn't work.

That aside the casting announcements have begun. From Comic Book Movie:

According to Moviehole 'Little Black Book' star Brittany Murphy has signed up for a sequel in the Sin City franchise.

"I'm absolutely thrilled. It's exciting to be a part of something so big and artistically groundbreaking", says the actress, who played Shellie in Robert Rodriguez's film transfer of the Frank Miller comic.

"I love the film and I'm ecstatic to be working with director Robert Rodriguez and the crew again."

I'm not so concerned about that casting, what I am excited about though is the announcement that Marv is back, for me Mickey Rourke stole the movie, he was superb. Now we just have to sit tight and see who else is coming back, unfortunately the second best thing about that movie can't, I just have to hope that the bad actors don't make it back...unfortunately they are some of the ones left alive.
