Though it’s tough to take director Robert Rodriguez at his word given how many times we’ve been promised that Sin City 2 is “right around the corner” over the past few years, he’s finally making good on two follow-ups this summer: Machete Kills and Sin City: A Dame to Kill For.  With production looming closer on both films, the first promo posters have now gone online.  Rodriguez will first shoot the Machete sequel Machete Kills this month, which finds Danny Trejo returning as the murderous Mexican.  Other returning actors include Michelle Rodriguez and Jessica Alba, who will be joined by newcomers Mel Gibson, Demian Bichir, Amber Heard, and recent addition Sofia Vergara.  Then, Rodriguez will finally shoot the Sin City follow-up, Sin City: A Dame to Kill For.  Hit the jump for more.sin-city-2-sequel-imageWhile the posters don’t necessarily reflect what the final product will look like, it’s nice to get a tease of what’s to come.  Notably, the poster for Sin City: A Dame to Kill For confirms that Frank Miller will be returning as co-director alongside Rodriguez.  Mickey Rourke and Rosario Dawson are both confirmed to be reprising their roles, and we’ll surely be hearing more casting announcements over the next few weeks.  Story details are under wraps, but Rodriguez previously revealed that the film would involve three separate stories from Miller: A Dame to Kill For and two new ones that have yet to be announced.Here are the promo posters, courtesy of c7nema and NicoFilmosphere (via The Playlist):sin-city-a-dame-to-kill-for-postermachete-kills-poster
