Frank Miller spoke with Rotten Tomatoes to kill the rumor that Sin City 2 wasn’t happening because of Grindhouse. Miller told them plainly, “The script is written and Robert and I are raring to go, but it looks like I’m going to be doing The Spirit first and Robert’s going to be doing Barbarella first.”
Now, with more traditional filmmakers, I might be inclined to think that they won’t come back to it, since they have both moved on to other projects…but Robert Rodriguez and Frank Miller aren’t traditional filmmakers. Rodriguez works so quickly that I won’t be surprised at all to see him back on this project, and I’m sure that Frank is just too darn excited to wait to work on his first solo film.
We’ll see what happens, but the box office for Grindhouse should not and will not have an affect on Sin City 2. Sin City was a success, there’s no reason that a completely unrelated (and WAY TOO LONG) project like Grindhouse would put a stopper in it.
