Anyone clamoring for another wild 3D romp from the mind of Robert Rodriguez is in luck. Spy Kids 4: All the Time in the World is now shooting in Austin, Texas in anticipation of a August 19, 2011 release date. Rodriguez is not only directing from his own screenplay but will also serve as producer, director of photography, editor and visual effects supervisor. The film stars Jessica Alba as a retired secret agent, married to Joel McHale, who is called back into action when the the villainous Timekeeper (played by Jeremy Piven) threatens to take over the world. It’ll also feature the return of Antonio Banderas, Danny Trejo and the original Spy Kids Alexa Vega and Daryl Sabara, though they aren’t the stars. Read the full plot description and more after the jump.

Here’s the official plot description of Spy Kids 4: All the Time in the World:

On the surface, Marissa Cortez Wilson (Jessica Alba) has it all…married to a famous spy hunting television reporter, a new baby and intelligent twin step kids. But in reality, trying to mother Rebecca (Rowan Blanchard) and Cecil (Mason Cook), who clearly don’t want her around, is her toughest challenge yet. Also, her husband, Wilbur (Joel McHale), wouldn’t know a spy if he lived with one which is exactly the case – Marissa’s a retired secret agent. Marissa’s world is turned upside down when the maniacal Timekeeper (Jeremy Piven) threatens to take over the planet and she’s called back into action by the head of OSS, home of the greatest spies and where the now-defunct Spy Kids division was created. With Armageddon quickly approaching, Rebecca and Cecil are thrust into action when they learn their boring stepmom was once a top agent and now the world’s most competitive ten year olds are forced to put their bickering aside and rely on their wits. With a little help from a couple of very familiar Spy Kids, Carmen (Alexa Vega) and Juni Cortez (Daryl Sabara), and some mind-blowing gadgets, they just may be able to save the world and possibly bring their family together while they’re at it.

Several months ago, Dimension announced they were prepping a fourth Spy Kids film and Rodriguez said that it was basically ready to go as a reboot. However, things got bumped back when the Desperado director decided to make Machete and produce Predators. Now he’s back on schedule.

And if that schedule continues, once Rodriguez is done with Spy Kids 4, he’ll get to work on Sin City 2 At least, that’s what he said. But who knows with Rodriguez. If you had your own film studio in your backyard, you’d tend to go off on tangents too.

Is Robert Rodriguez still on the list of can’t-do-wrong directors? And will you rush out to see Spy Kids 4, or do you prefer the filmmaker’s more adult fare over his kiddie stuff?
