Spy Kids 4: All the Time in the World (2011)

Spy Kids: All the Time in the World (often referred to as Spy Kids 4D, also known as Spy Kids 4: All the Time in the World and Spy Kids 4D: All the Time in the World) is an upcoming American 4D action-adventure family film directed by Robert Rodriguez and the fourth installment in the Spy Kids series. It is currently set to be released on August 19, 2011. Filming began on October 27, 2010. It will be the first of the series that uses "Aromascope" that allows people to smell odors and aromas from the film via scratch & sniff cards (reminiscent of the infamous 1960s Smell-O-Vision) last used theatrically in the 2003 animated film Rugrats Go Wild.

The film revolves around twins named Rebecca and Cecil (Rowan Blanchard and Mason Cook), who have no respect for their stepmom, Marissa Cortez Wilson (Jessica Alba), the wife of spy-hunting reporter Wilbur Wilson (Joel McHale). Unbeknown to the twins, Marissa is a retired agent for the OSS (Organization of Super Spies) which has since become the world's top spy agency and former HQ of the now-defunct Spy Kids division. When Earth is threatened by an organization led by a hyperion mastermind known as "the Timekeeper" (Jeremy Piven), she is contacted and called back into action by the OSS, leaving a red-sapphire necklace (the key to the Timekeeper's plan) with Rebecca. However, with the end of the world pending and the necklace stolen by the Timekeeper, both Rebecca and Cecil find that they have no choice but take part in the battle, help Marissa, and put their anger against her aside to rescue people's lives that are at stake while enlisting the help of the previous Spy Kids Carmen and Juni Cortez (Alexa Vega and Daryl Sabara).
