Speaking at this year's SXSW film festival, Robert Rodriguez promised that the long awaited sequel to 'Sin City' will shoot this summer, following his directorial duties on another sequel: 'Machete Kills.' But he's been saying that for years. Will it actually happen this time?

Empire has the scoop on yet another guaranteed start date for the film, which has been consistently pushed back for years in favor of other more feasible projects. The film will include the story 'A Dame to Kill For,' which once again centers on Marv, played by Mickey Rourke, and two new Frank Miller scripts that were never published in the series.

Rodriguez offered, "We'll probably be editing 'Machete' while we shoot 'Sin City.' It'll be summer and it'll be hot, so it'll be nice and cool inside with all the green screens." Rodriguez knows what's important when shooting films in Texas: central air. Let's just hope his AC system doesn't break down, thus pushing 'Sin City 2' back another four years.

There's also no confirmation of casting, including the imperative return of Mickey Rourke as Marv. Summer starts early in Texas, Rodriguez, and you can't cast Danny Trejo in every role like a Hispanic Eddie Murphy.
