The film takes place in October of 1957, when America had plenty to be worried about. Rock 'n' roll. Television. The bomb. And on the fourth day of that month, the Soviets successfully launched the first manmade satellite, Sputnik, into orbit. The space race had officially begun. The Cold War just got colder. People were unsure about their neighbors, even questioning their friends. In the small town of Rockwell, Maine, Annie Hughes (voice of Jennifer Aniston) is just worried about putting supper on the table for herself and her nine-year-old son, Hogarth (voice of Eli Marienthal). A single mother holding down a job at the local diner, Annie has her hands full with Hogarth--headstrong and imaginative, always on the lookout for the latest attempted takeover by mutant aliens or subversive invaders. So when a local fisherman comes into the diner with a tall tale about a huge metal man falling into the sea, the only one to pay him much attention is Hogarth, who sets out exploring to find the enormous robot. What he does find is a 50-foot giant with an insatiable appetite for metal and a childlike curiosity about its new world. Rumors of everything from an alien invasion to a Russian secret weapon bent on destroying Rockwell soon spread through the small town, prompting the arrival of government agent Kent Mansley (voiced by Christopher McDonald). Keeping one step ahead of Mansley, Hogarth convinces his beatnik friend Dean (voiced by Harry Connick, Jr.) to hide the Iron Giant (voiced by Vin Diesel) in Dean's junkyard. But it isn't long before the rumors turn into paranoia--the situation escalates and the possible destruction of Rockwell looms. Hogarth turns to his friend, the Iron Giant, who ultimately finds its humanity by unselfishly saving the town's residents from their own fears and prejudices.
