Factual error: No airport in NYC has the view of the New York City skyline that Kevin has when he realizes that his family is in Florida and he's in New York.
Factual error: During the big Newsies rally when Medda is singing "High Times", as she is swinging, lighted exit signs can be seen. I don't believe that those were around in 1899.
Factual error: During the movie, Doug watches video from the previous Olympic competition. The skaters are shown performing in a darkened arena lit by spotlights. Special lighting effects like this are not allowed in competition. All competitions take place in a brightly lit arena.
Factual error: When Virginia Madsen's character sees Candyman in the mental hospital, a male nurse calls for the injection of 1000 milliliters of sedative to calm her down. 1000 milliliters is equal to 1 liter, which certainly could not be injected, let alone as fast as it was.
Factual error: The baby is expanded to approximately fifty times his height, width and girth but it's explicitly stated that he retains his orginal mass. This means he will have the same volume as one hundred and twenty five thousand babies of his original size, but will weigh the same as before he was enlarged! That child is going to weigh much less than the volume of air he displaces. He's going to float away.
Factual error: As the Thug Zombie is on top of the lawnmower and is getting hacked to bits, his body parts don't fly off. His arms would've gone everywhere when the blade reached his shoulders, and the same goes for his head. (01:29:15)
Factual error: Rosie is repeatedly shown buzzing in before Alex Trebek can even finish asking the question. In Jeopardy!, this isn't possible, you may only buzz in once the question is finished.
Factual error: Lt. Caffey (Tom Cruise) wants the two marines to plead guilty and take a deal because he doesn't want the to "spend the rest of their lives in Leavenworth (prison)." The United States Disciplinary Barracks is indeed located in Leavenworth, Kansas. And the US Army and US Air Force send convicted felons there to do their time. However, Marines and members of the United States Navy are sent to Portsmouth Naval Prison in New Hampshire. It is run by the Marines.
Factual error: The Nina, Pinta, and Santa Maria are shown starting back for Spain at the end of the first voyage. In fact, the Santa Maria had wrecked by this time; the return voyage would be made only by the Nina and the Pinta.
Factual error: At the very end of the movie, the Pope gives the nuns a standing ovation. The other people seated in the box with him should have immediately risen at this time. Instead, the man seated to his left looks up at him, seeing that the pontiff has stood, but makes no movement to join him on his feet.
Factual error: During the confrontation between Little Bill and English Bob outside the barber shop, all the Deputies cocked their guns - for emphasis. Then Mr. Beauchamp reaches into his bag to show that he only has books, the Deputies cock their guns again. With the rifles they have this would eject the shell that was in the barrel and cycle a new one. It doesn't.
Factual error: During the battle over the fort the British shoot a red flare into the sky. The British army learnt of the effectiveness of rocket weapons when fighting in India in the 1790s. In 1804, rockets (developed by Colonel William Congreve) were introduced into British service. The rocket flare was developed around this time (also by Colonel Congreve). This film is set in the 1750s - the British army would not have had rocket flares (source: Taylor, J.W.R (1970). Rockets & Missiles, Hamlyn, London. PP. 6-10). (00:34:30)
Factual error: Throughout the film, the drainpipes on the buildings are almost all plastic - the film is set in the Victorian era.
Factual error: When the aircraft window is shot out, depressurization of the plane occurs shortly after the door of the plane blows off. When depressurization occurs, the pressure in the fuselage drops. Why would the door blow-out now when it held before with higher (normal) pressure?
