Factual error: In the scene where the Iron Giant is spinning the boy around in a junk car he is holding, notice that the car resembles a 1959 Cadillac...however since the film is set around 1957, this is not a likely car to be found anywhere yet, much less a junk yard. (00:46:20)
Factual error: During the fight with the Giant, the USS Nautilus is preparing for a missile launch. In real life, the USS Nautilus (SSN-571) didn't have ballistic missile capabilities. In addition, if the submarine did, it would be of the Regulus missile type; a cruise missile fired by rockets and a ramp on the submarine. The film shows a Polaris-type missile being launched, which wouldn't have entered service until 1960-1961, well after the events of the movie (1957).
