Factual error: The Map of Europe used for plotting their route displays the Netherlands incorrectly, showing its two major central polders (low-lying reclaimed landmasses surrounded by dikes) which weren't drained and finally completed until 1968.
Factual error: The detective played by Rory Kinnear is shown in 1951 typing a request for Alan Turing's military records. He changes a name with correcting fluid - unknown in the UK in 1951.
Factual error: Chris Kyle did not make Chief after his first deployment. He made Chief during his fourth deployment.
Continuity mistake: When Cheryl emerges from the store and begins talking to the club representative distributing flyers, the lemonade she is holding has the cap off in one shot, then on in the next. It switches hands and then disappears entirely. The flyer she holds also switches hands.
Continuity mistake: Soon after Jane meets Stephen at the beginning of the film she writes her telephone number on a napkin. Later when he looks at the number it is written much more clearly.
Factual error: "Can't take my eyes off you" was released in May 1967. The recording scene of this song shows an Ampeg SVT amplifier in the background. Ampeg SVT was not available before 1969 and the specific model shown on the scene (with white rocker toggle) is a later 1976-1979 model. (01:54:10)
Continuity mistake: Ben Bart passed away earlier in the film but can be seen dancing on stage with the character Gertrude, at a James Brown concert where he is performing "I Got Soul (Super Bad) ". (01:46:00)
Suggested correction: During that sequence, they intercut James in his gold jumpsuit, with long hanging-down hair, and James in a black-and-white checked vest, doing the same song. In the black-and-white vest era, Ben Bart is still alive, so the dancing could have been from that era.
While that does seem to be the case, it should be pointed out that Ben Bart died in 1968, but the song James Brown is singing, "Super Bad", was recorded in 1970.
Factual error: The helicopter flown is a Bell 407. The movie is set in '88 and the first flight of this type was 1994.
Factual error: Brian Wilson's panic attack on the airplane takes place circa 1964. However, the interior of the plane had distinctive sculpted doors on the overhead bins, a style first introduced in 1983 on the Boeing 757.
Factual error: As the marchers start through the streets before they gather at the Edmund Pettis Bridge, they pass by a shop with a Pepsi sign. The Pepsi logo, however, is from the 1980s-1990s.
Factual error: When the Doctor visits William Turner in Chelsea, he claims to be leaving by train from Charing Cross. That station did not open until 1864 - 13 years after the death of Turner.
Factual error: Roland enters the train to go to the war, in 1914, with "Spanish Flu", but that was the (wrong) name given to the 1918 flu pandemic, which lasted from spring 1918 through spring or early summer 1919.
Continuity mistake: Master Lui at his first appearance in the movie kills the traitor slicing his throat with burning tongs which he points right away at the eyes of the protagonist. Sammo Hung's grip on the tongs changes between shots. (00:11:00)
Continuity mistake: Rich is dangling a light bulb above his dad's head. When the camera shifts to a close-up of Rich, the light bulb is higher - almost across from his own face - but back to dangling above his dad's head with the next camera shift. This is independent of Rich's dad telling him to "hold the light steady." (00:06:23)
Continuity mistake: Throughout the film, Nicole Kidman's hair changes color. In one particular dinner scene, her hair is everything from light blonde, to dark blonde, to red.
Factual error: In the opening scenes where Margaret drives to San Francisco, her car is an early 50s Meteor. Meteors were a Ford Motor Company brand just above Ford (a bit like Mercury) but were sold only in Canada. Meteors often were only rebadged Fords, like this early 50s model. The rest of 50s and 60s car choices in the film seemed perfect.
