Factual error: The helmet is a Cooper/Bauer HH3000 that wasn't made until 1989 or 1990. (00:26:30)
Factual error: When they are playing hockey in the driveway, the FBI agent says he lived in the city in St. Louis. He then says they had street names like 1st street, 2nd street, Washington, Lincoln. First and Second street exist, but they are both in industrial areas and no-one ever talks about them. More to the point, there is no Lincoln Street in St. Louis at all. (00:27:00 - 00:28:00)
