MTV talked to Frank Miller who talked a bit about the Sin City 2 delay and that they are planning to do Sin City 3 as well:
“There was just some problems above us that I don’t understand that I dont really want to understand,” Miller said matter of factly about studio delays in pre-production. All of which shouldn’t bum out fans, he insisted, since”he expects not only to eventually film “Sin City 2,” but “Sin City 3 as well. That story, Rodriguez divulged, would concentrate on Miller’s “Hell and Back,” the story of a hallucinating artist named Wallace. Rumors have persisted for months that the role of Wallace was being written for Johnny Depp, a casting coup that Rodriguez himself was coyly confident would eventually happen.
