Factual error: In the scene where Vince returns to his dorm room and finds Dennis Franks has moved in, Franks informs him that Coach Vermil is mixing the veterans with the rookies. In 1976, Dennis Franks and Vince Papale were both rookies.
Factual error: Louis Simo gives his son an Etch-A-Sketch while taking him to school, and later when Louis stops by to see his son at his ex-wife's house, his son is playing with the Etch-A-Sketch in his bedroom. Both incidents take place in the summer of 1959. George Reeves died June 16, 1959, hence the investigation. The first Etch-A-Sketch toys were produced on July 12, 1960 and Ohio Art launched the toy in the United States in time for the 1960 holiday season.
Factual error: When Chris is running from the cabbie he jumps into a train, and in the process gets his scanner stuck in the door, which he loses hold of as the train begins to move. BART trains will not move unless all doors are secure, so this could not have happened. (00:30:00)
Factual error: Marie Antoinette has moved into her new vacation home following the birth of her daughter. Her friends are visiting, she is walking through the field of wildflowers, and she blows a ladybug off her finger. The camera pans upward to show her gazing at the sky. There is a very obvious vapor-trail from a large airliner cutting through the center of the camera shot, from one side of the screen to the opposite, predating jet-liners by over 150 years. (01:25:25)
Factual error: The Blairs are in a car travelling down the motorway when Tony receives a phone call from a lord. In the background the passing scenery is leafless trees and a bare winter landscape, but the events of the film take place during the English summer.
Factual error: On the way into the health spa, Wilberforce's friend says they should hurry or they'll be late. Wilberforce replies "the waters have been here for a million years - how could we be late?". In the late 1700s, no-one in Europe thought the world was that old.
Factual error: To demonstrate his hatred of the England football team, Paul throws darts at a photograph of the players in their red shirts midway through the competition. However, the photo in question was taken after the final was played. Furthermore, in relation to the film's timescale, when the scene takes place neither the team or the choice of kit had been decided upon.
Factual error: Ron Clark was from Aurora North Carolina. The shot where he is leaving for New York is supposed to be in Aurora, which is in Eastern North Carolina. The shot shows a house with lots of spruce trees around it. We don't have those in Eastern North Carolina.
