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: There is a scene with his baby, Ray Jr. has a butterfly shaped pacifier in his mouth. They didn't have butterfly pacifiers then - just plain old pacifiers were available.
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: On a number of occasions uniformed Wermacht officers and men are shown saluting Albert Speer. Speer was a civilian and (obviously) not in uniform. Military men do not salute civilians.
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: The backdrop to the party scene in India shows a large building with glass windows. The Romans were the first to use glass windows some 300 years later.
Factual error: This film shows Sellers faking a broken leg in order to get out of playing the pilot in Dr. Strangelove. Sellers fell off a ladder on the set of the film, and director Stanley Kubrick was there to see it happen. He broke his leg and was replaced by Slim Pickens as a result.
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 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: In this scene several sailors attack Alice Paul and tear down the demonstrator's banners. The older sailor's petty officer rank specialty insignia featuring three lightning bolts, Radioman, was not created until 1921, four years after this incident. (01:30:35)
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.
Factual error: After Deni fires the last shot in her pistol, she continues to pull the trigger and the gun continues to click. However, this would not happen in a single-action semi-automatic like the Glock she is firing.
Suggested correction: Speer, in his capacity as Reichsminister of Armaments and Munitions, would have been very recognizable to all Germans at this time and respected. Additionally, no Wehrmacht members actually salute or interact with Speer (by my memory), only Waffen-SS, who would doubtless be more loyal to a senior party member and willing to salute him. More so, if the entry refers to the Hitlergruß, the Hitlergruß was given regardless of rank per National Socialist ideology related to social equality.
One of Speer's many defences at his postwar trial was that he was a civilian, mistrusted by the military and never accorded military courtesies, which included them saluting him.
