If 'Sin City' wasn't your thing, you can still probably appreciate one thing about Robert Rodriguez's movie: Jessica Alba as a stripper. Well, get ready Jessica Alba fans because she says 'Sin City 2' will feature even more of her stripper Nancy Callahan including some new dance moves that Alba calls "crazy."

'Sin City: A Dame to Kill For' is about to begin filming in Austin, Texas and Jessica Alba is one of the cast members from the original film set to return for the sequel. In the comic the film is based on, Nancy is only a background character but you can expect to see a lot more of Alba-as-stripper in 'Sin City 2.' The actress had this to say about her new moves to Vulture:

I had to learn a bunch of dance sequences for it. I do a lot more dancing in this one. It was kind of crazy. It was very, very difficult, and you'll see why.

For those of you out there hoping, wishing, waiting for Jessica Alba to appear nude in 'Sin City 2,' we have some bad news for you: it's not gonna happen. While it looks like Alba has some seriously sexy moves in store for the sequel, she was asked to appear nude in the first 'Sin City' and pointed to a strict "no-nudity clause" in her contract. Alba told Elle in 2006:

I don't do nudity. I just don't. Maybe that makes me a bad actress. Maybe I won't get hired in some things.

(If you're wondering what this means to her shower scene in 'Machete' - she was wearing a bathing suit in that scene was digitally altered to make it appear like she was nude.)

'Sin City: A Dame to Kill For' is schedule for release on October 4th and co-stars Joseph Gordon-Levitt, Josh Brolin, Rosario Dawson, Ray Liotta, Juno Temple, Jeremy Piven and Bruce Willis. If you just can't wait, you can watch Alba's big stripping scene from the first film below.
