The Spy Kids 4: All The Time in the World is a sequel to Spy Kids films I, II, and III. However this movie can stand on its own. At the beginning of this movie we see an action packed scene where a pregnant spy, Marissa chases down bad guys and then retires to raise her family. What you need to know is that there were Spy Kids prior to this movie but they were closed down due to budget cuts. At OSS, the secret agency headquarters, there exist artifacts of the former Spy Kids' action equipment. Unfortunately for the twins, Rebecca and Cecil they are inactivated.
Rebecca and Cecil are her, Marissa's, step children, who is the aunt to the original Spy Kids. She is married to Wilber who's a reporter seeking to expose spies. As the story unfolds we find that the pendant, the Chronos Sapphire that Marissa gives to Rebecca is the key to an Armageddon plot by Tick Tock and the time keeper. Many chase scenes and escapades ensue between these kids and bad guys.
Marissa's former spy profession is revealed when the step kids are under attack. An automatic security system is secretly in place in their home with the dog, Argonaut a robot assigned to protect them. This system is triggered and now the children believe their aunt is cool. They arrive safely at OSS headquarters and explore the former Spy Kids' room. The now grown up former Spy Kids are asked to take action against this international villain. They are stymied by the time keeper and his bad guys.
The step children Rebecca and Cecil, meanwhile safely at OSS are called on their first assignment; they must stop the time keeper, hold off Armageddon and get the Chronos Sapphire. The kids must prove to the world that they deserve to be the next generation Spy Kids. They must save the world in time.
I am admittedly not a fan of 3D movies. Generally the movie isn't enhanced by 3D effects enough to warrant sitting in a theater with cheap plastic glasses on one's face for two hours (or three, if you're seeing "Avatar"). But 4D movies? Now we might be on to something. Apparently, a company in South Korea wants to provide America with fully equipped 4D theaters over the next couple of years. What exactly does 4D entertainment entail? Well, these theaters would feature moving chairs that vibrate (the official term seems to be "back ticklers," which just sounds dirty), strobe lights, and nozzles that can spray anything from a refreshing mist to bubbles to any of 1,000 different scents.
Give director Robert Rodriguez this: no one in their right mind would ever call him one-dimensional. For every gritty, slam-bang action flick he makes that turns a big, big box-office profit, he's on the cusp of his fourth film in the marketable, critically loved "Spy Kids" franchise with "Spy Kids: All The Time In The World." This one stars Jessica Alba ("Sin City," "Machete," "Fantastic Four") as an ex-spy-turned-wife-and-stepmother (to a spy-hunting TV reporter) whose kids have just been recruited into the Spy Kids organization.
