Factual error: When Hughes flies the open cockpit H-1 at over 350mph he isn't wearing goggles. There isn't a sign of any wind at all in the cockpit. Even with a windscreen, the wind would cause your eyes to water well before 350mph.
Factual error: When they show the Nelson Eddy song 'I Love You', the set/movie shown is Rose-Marie. But that number is from Rosalie not Rose-Marie. Two totally different movies - one set in West Point not with the Canadian Mounties. There are no Cole Porter songs in Rose-Marie, likewise there are no Mounties in Rosalie. Rose-Marie's music was by Harbach / Hammerstein II / Friml / Stothart. (01:09:25)
Factual error: When Ray and several others are riding in an automobile they pass underneath a railroad bridge. Passing over them on the bridge is a modern day container type train, a train of the era that the film portrays would be made up mainly of boxcars, tank cars, etc. not shipping containers.
Factual error: The movie is set in Rwanda in 1994. At the start of the movie you see a billboard advert for MTN, a South African cellular service provider that was not available in Rwanda in 1994.
Factual error: In the cricket match, a number of things happen that are highly questionable. When the player is bowled, the bowler appeals, something that is only done if the umpire's opinion is required, which in this case it isn't. Even after the appeal, the umpire shakes his head, which in cricket, indicates that the batsman is not out. Only a raised finger or perhaps a nod would be out. To the uninitiated, the equivalent in baseball would be for the umpire to call "ball" and have the batsman walk off the ground as though he had struck out, instead of taking first base. (00:33:10)
Factual error: Just before old Ptolemy starts telling his story of Alexander, at the very beginning of the movie, we see a shot of the famous Lighthouse of Alexandria. It's fully operational, which is a mistake because the building was finished during the reign of Ptolemy's son, Ptolemy II Philadelphos, some years after the first Ptolemy's death.
Factual error: Before 1949, when the part of the film set in Hollywood takes place, the famous sign on the mountain read "Hollywoodland", not "Hollywood". The sign had been allowed to deteriorate and during that year, the Hollywood Chamber of Commerce offered to remove the last four letters and repair the rest.
Factual error: In the scene where a chemist is preparing a solution to give to Mrs. Goebbels which she uses to kill her six children, the chemist is holding a modern day conical flask with the brand name "Schott" marked on it. Flasks pre-1950's did not have these markings.
Factual error: In the scene of reaching Machu Pichu, the asthmatic Che Guevara is practically running up (6.000 meters high), and his friend, who doesn't suffer from any respiratory illness, is gasping for air. In other scenes, the asthma plays an important role in the film.
Factual error: A scene in the second half of the film pans up over the top of the Flamingo hotel/casino facing north up the Vegas strip. The Caesars Palace sign is to the left (west) and north of the Flamingo are the Sands, the Dunes, and the Frontier casinos in that order. The Dunes hotel/casino was never located between the Sands and the Frontier. It was in fact one of the southernmost located casinos on the strip at that time and would have technically been behind, southwest of, the Flamingo in this scene.
