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.
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 and a cut off sloppy Joe sweatshirt, both ridiculously anachronistic - Sixties hipster fashions - and nowhere even close to a World War 2 uniform.
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: When Eliot Ness is at Jim Malone's house for the first time, Malone's collar is opened, then buttoned, then open again.
Continuity mistake: When the soldiers arrive at the Alamo, the soldier with the glasses is reading a book with a white cover. In the next shot, he is reading one with a red cover.
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.AndrÃ© VinÃcius
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.
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.
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)
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.
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).

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)THGhost
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)
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.
Factual error: The ribbon of Richard Burton's Distinguished Flying Cross is on upside down. The Air Force Cross following it is the right way up. The stripes on both should point the same way, as they do on the uniform of his colleague in the mess. Nobody would be allowed to get away with a mistake like this - another officer or senior NCO would soon point it out. In addition, as a long-service veteran (his colleague says he served in the Battle of Britain) he should be wearing the ribbon of the 1939-1944 Star (as it was then), which was issued to all qualified personnel from 1943.Necrothesp
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.
