Robert Rodriguez has been talking up a potential sequel to Sin City since very shortly after the first film debuted in 2005.  For the last half-decade, he and co-director Frank Miller will offer a hopeful update on Sin City 2 seemingly ever few months, and the would-be movie is almost always tantalizingly close to production, according to the independently-minded director and medium-redefining comic book writer/artist.  It should come as no surprise, then, that at his Comic-Con panel today, Rodriguez made some optimistic statements about Sin City 2.  What might be a bit more surprising, however, is that he also announced two Machete sequels, Machete Kills and Machete Kills Again.  There's more, though: Rodriguez is now behind the latest attempt at a new version of Heavy Metal.

So apparently Robert Rodriguez gave in to overwhelming public demand for another installment of his family franchise, finally writing and directing Spy Kids 4: All the Time in the World.  In the sequel, Jessica Alba plays and ex-spy stepmother attempting to raise her new baby and connect with her twin stepkids, played by Rowan Blanchard and Mason Cook.  When Jeremy Piven's villainous Timekeeper gets up to no good, the whole family, including Joel McHale as Spy Dad, are swept up into, you know, juvenile espionage.  As if to confirm that this is indeed a real thing, Dimension has released the first image from Spy Kids 4.

Joel McHale is set to join Robert Rodriguez's Sky Kids 4: All the Time in the World, reports Variety. The comedian, best known for hosting "The Soup" and his recent breakout role in NBC's "Community", joins Jessica Alba in the film, which will be released in 3D next summer.

Sin City vixen, Jessica Alba, is looking to reteam with director Robert Rodriguez for Spy Kids 4: All the Time in the World, reports Heat Vision Blog. The two previously worked together on Sin City and more recently, Machete, which comes out in September.
