Factual error: While handling the ignition coil cable to the distributor cap, Joe Pesci tells De Niro that the timing chain needs adjustment in his truck. A truck of that year with an inline Chevy motor would not have a timing chain at all, instead this truck would be equipped with a direct drive timing gear. Even if it had a timing chain, it would be behind the water pump and a cover. It would have been a several hour job to replace, not possible to adjust it.
Deliberate mistake: The Messerschmitts have painted yellow fronts, this wasn't done by the Germans until after Dunkirk. Christopher Nolan has admitted doing this deliberately so the audience could tell the difference between the Spitfire and the Messerschmitt during the combat scenes.
Factual error: Why is Hilts not wearing a uniform? A serving officer captured behind enemy lines in civilian clothing risked being shot as a spy. If a prisoner's uniform was too worn or damaged to wear, it was routine for the German authorities to replace it - a P.O.W. in civilian clothes is an obvious escape risk. He is wearing a pair of tan chinos, a cut off sloppy Joe sweatshirt, both ridiculously anachronistic - Sixties hipster fashions - and nowhere even close to a World War 2 uniform. He is also wearing Army Type III Service boots - something that would never have been issued to a fighter pilot.
Factual error: The interior shots of the Gemini and Apollo Spacecraft show worn and dirty panels, knobs, switches and circuit breakers. The movie most likely used some original cockpit trainers, but in reality the astronauts were flying brand new spacecraft that were spotless.
Continuity mistake: Angelica has flowers on her dress. During the wedding, they disappear and reappear between shots.
Revealing mistake: In the final scene where Fonda and Holbrook are looking over the carrier at the crowds on the dock you can see that only the first rows of people are dressed in period clothes, the rest of the crowd are dressed as they would have been in 1976 when the film was made.
Continuity mistake: When Eliot Ness is at Jim Malone's house for the first time, Malone's collar is opened, then buttoned, then open again.
Revealing mistake: When Mr Witt rides out of the Zulu camp in a 2 horse cart at the beginning of the movie, just before it exits, you can see it's a stunt double at the reins.
Continuity mistake: When the police are moving in to arrest Dzhokhar Tsarnaev, the shot shows an FBI SWAT officer grabbing him. But in the next cut, the officer changes to a Boston Police Officer while changing back to a FBI Officer in the following shot.
Factual error: Before receiving the North American P-51D Mustangs, the Red Tail squadron was using the Curtiss P-40E Warhawk. The movie shows the Warhawks being able to keep up with the German Bf 109 G-6s quite easily, fighting on even terms. In reality, the Bf 109 G-6 could easily outperform the Warhawk, being able to easily outrun and out-turn the Warhawk. Still, the Bf 109s are no match for the Warhawks.
Factual error: Robert McNamara is wearing a multi colored Polo shirt talking to Mrs. Graham in 1971. The Ralph Lauren Company did not make the shirts until 1972.
Other mistake: When the Japanese planes take off for Pearl Harbor, some of the 3 man torpedo planes only have a pilot.
Visible crew/equipment: Near the end of the movie when the convoy is heading back to the Pakistan Stadium, a Humvee stops briefly to allow a man to walk across the street with a child in his arms. When the shot changes and the Humvee begins driving again, a crew member or cameraman is seen inside the Humvee wearing a white shirt. All of the men who entered the Humvee were wearing fatigues. (02:05:27)
Factual error: Frank, Archie and Snowy are all rural boys from New South Wales, but they all play Australian Rules football expertly. In 1915 Australian Rules was almost unknown outside of Melbourne. In a time before television or film they wouldn't even know what the ball looked like. In fact the game was only established in Sydney in the 1980s, and is still not terribly popular there. There is no way that three people from New South Wales would know how to play the game in 1915, let alone with such skill.
Factual error: When the map of the German advance is shown, Switzerland is shown to be taken over. Switzerland was never invaded by the Germans. (00:05:10)
Suggested correction: It doesn't show German advances. It shows the German influence over Europe, symbolizing it covers all of Europe and then expanded towards the East. Italy was never conquered by the Germans either yet it was part of the axis and is shown being covered by black. Switzerland, though neutral, was fully surrounded by the Axis and their influence played heavily upon the country. Its a very crude simulation.
Suggested correction: It does not show the German advancement in true historical order, but more like a red shadow that expands across Europe in a steady pace. And just as the camera starts zooming in on Stalingrad, you can see a small sliver of red starting to spread on the south-eastern coast of Norway.
Revealing mistake: Near the end when Ace gets into his Cadillac, in the first shot facing the front of the car, there is a protective glass in front of Ace (the same width as the windshield) with the dashboard in between that glass and the windshield. Note the vertical edge of the glass is visible at the right side, and the rearview mirror's sticker on the windshield casts a shadow onto the second glass. During the stunt, the flames on the dashboard are between the glass shield and the windshield, keeping the actor safe from harm. (02:46:05)
Factual error: Most of the parachutes are PX type. These came out in the 1960s. They only used X type during the war - only a few of those are seen in the film. (00:07:00)
Visible crew/equipment: As Achilles' ship nears the Trojan shores, Agamemnon snidely asks, "What's the fool doing? He's going to take the beach of Troy with fifty men?" At the start of the next shot, as the camera begins to pan down, on the far right, just beside a person's (who is dressed in blue) head is a metal bullhorn (ie. used to give instructions to cast/crew, and which definitely doesn't belong in this time period). (00:36:35)
Continuity mistake: When Eduardo finds the letter on the mantlepiece about them apparently stealing the idea for Facebook and asks Mark if they did or not, he places a bottle on the mantlepiece just before he finds the letter. This bottle rotates slightly between shots without him touching it after placing it down. (00:49:15)
Revealing mistake: When the 54th Mass. marches past a liberated plantation some black children wave them on. One of them is wearing a digital wristwatch.
Suggested correction: The character of Hilts was based (in part) on the life of a British OSS agent who managed to pass as pilot by stealing a flight jacket (revealed in the DVD). We can only assume that since the Germans believed the camp was escape-proof, it didn't matter what Hilts was wearing, since he wouldn't be going anywhere.
Cobblers. Hilts is wearing casual clothing typical of the time the film was shot, not when it was set. No prisoner of war would be dressed the way he was. The posting is correct.
I've always assumed that the actor, Steve McQueen, insisted on the outfit so he would look hip per his image. He had a reputation for being a prima donna on set.
