Just when you thought the world was safe, danger returns this summer with the release of 'Spy Kids: All the Time in the World in 4D.'

Jessica Alba stars as Marissa Cortez Wilson, a retired spy now entrusted with a young family of her own, who gets called back into action when the fate of the planet is threatened by a monstrous villain, a "magical terrorist" called the Timekeeper (played by Jeremy Piven). All the while, her husband (played by Joel McHale) and stepkids have no idea what she used to get up to before they came along: working for OSS, the Organization of Super Spies -- the former headquarters of the Spy Kids division.

Moviefone has your exclusive first look at the poster for 'Spy Kids 4,' showcasing the 4-foot-high butt-kickers coming right at ya!

As if battling evil and confronting the possible end of the world weren't trouble enough, Marissa must do so with sippy-cup in tow, her own new baby strapped to her front and two difficult, squabbling twins, Rebecca and Cecil (Rowan Blanchard and Mason Cook), who don't think all that much of her. Inevitably, we bet, such antics will serve to bring the stepfamily together and help mom get a little of the respect she deserves.

Directed by Robert Rodriguez, 'Spy Kids 4' also features the familiar faces of Antonio Banderas, Danny Trejo and the original Spy Kids, Daryl Sabara and Alexa Vega.

'Spy Kids: All the Time in the World in 4D' opens on Aug. 19 in 3D.
