The prepubescent, globetrotting, super-spy sibling duo from director Robert Rodriguez's surprise 2001 hit Spy Kids is back to save the world for a second time in this bigger-budget, larger-scale sequel. Spy Kids 2: Island of Lost Dreams opens with our heroes Carmen and Juni (Alexa Vega and Daryl Sabara), now official OSS agents, in the midst of another crisis situation: They have to reclaim to the powerful Transmooker Device from the clutches of those who might try to use it to permanently disable energy on Earth. Their quest leads them to the tropical lair of Romero (Steve Buscemi), an unhinged scientist who retreated into seclusion after a daring experiment backfired on him -- as well as on a whole breed of mutant creatures. As if finding the Transmooker weren't enough, Carmen and Juni have to contend with another set of mini-spies, Gary and Gerti Giggles (Matt O'Leary and Emily Osment), who are eager to one-up the world's most-respected spy kids. Returning to Spy Kids 2 are parents Antonio Banderas and Carla Gugino, as well as the evil-doers of the first film, Alan Cummings and Tony Shalhoub.
