Factual error: When Nancy goes in a car in London to score drugs there is a political poster stating 'Labour Isn't Working'. This poster was used by the Conservative party in the 1979 general election - Nancy was killed 9 months prior to this election.
Factual error: Warren Beatty refers to the "Hoover Dam" being able to generate the power needed for Las Vegas and his Flamingo casino. The problem is that he supposedly made the comment in 1937. At that time, the "Hoover Dam" was still called "Boulder Dam." It wasn't renamed to honour President Herbert Hoover until about ten years later.
Factual error: In one scene supposedly set in the late '70s (Andy was about to get/just got "Taxi"), Andy is playing Ms. Pac Man. I may be wrong here, but didn't Ms. Pac-Man come out in 1982 or 1983? (00:29:30)
Factual error: In at least two scenes, cars from the 1990's can be seen, despite the fact that the film took place two decades earlier. (00:50:00)
Factual error: In the final scene where Solomon was reunited with his family, the doors he entered the room through had Edwardian style leadlight glass. The movie was set about 50 years before this style.
Factual error: During Lee Iacocca's slide presentation to Henry Ford II in 1963, there are two slides that reference James Bond. One shows him standing next to the Aston Martin DB5, which made its debut in "Goldfinger" in 1964, and another shows a still image from "Thunderball", which was released in 1965.wizard_of_gore
Factual error: When the camera took a shot on a train coming to a station in Czechoslovakia, you can see electric cables above the train tracks. There was no such thing in Czechoslovakia as electrified trains in the 1940's. The electrification started in the 1950's. (00:01:05)
Factual error: An old man appears with children following him. This is supposed to be pedagogue Janusz Korczak. It appeared as if he was just wearing a suit and a Jewish arm band. In the Warsaw Ghetto, Mr. Korczak never wore an arm band and wore his WWI Polish Army Uniform, both as acts of defiance. He was beaten and almost put to death (he had connections) for not wearing an arm band so having one on in the movie is inaccurate.
Factual error: In the early part of the movie, there is a shot of the outside of Triple O's bar. The scene takes place in 1975 and "Coors" is advertised on the outside of the bar. Coors beer was not available in Boston/East Coast in 1975. It was only available from the 1980's.
Factual error: As Wendell and Jackie are driving in the car, Jackie turns the radio on to put a hiatus on their discussion. As soon as he turns it on, sound issues forth, but in the 40's radios used vacuum tubes, which required a warm-up period.
Factual error: When Jordan tries to escape with his daughter in the Mercedes, he pulls the parking brake with his hand (a hand-type parking brake) to stop the car, but that car (Mercedes Benz SL Class R129) is only available with a foot-type parking brake, making his action impossible.

Factual error: Joan's brother Pierre did not die at the fight at Paris. He actually outlived her and testified at her Trial of Rehabilitation.
