Factual error: The jacket blurb and plot synopsis for "Anthropoid" are historically and factually incorrect in stating that Heydrich was "third in command" of Nazi Germany. He was not; there was a chain of Nazi hierarchy above him and any historian of Nazi Germany will verify that. Unfortunately, Rotten Tomatoes perpetuates this inaccuracy by using the same jacket blurb in its own plot summary of the movie.
Factual error: When the characters are drowning on stakes in the ocean there is a modern yacht in the background.
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 Anita Hill is in her hotel room waiting to testify she is watching the Texas v. OU football game. In the movie the date for that scene is Friday, October 11, 1991. The Texas v. OU football game was played on Saturday, October 12, 1991.
Factual error: At the end of the film, Hellfire Jack returns the toy soldier to the son of the late William Hawkins in 1917. Hawkins son is shown taking it upstairs and placing it in front of a photo of his father, in between two medals. These are the British War and Victory Medals - these did not exist until 1919, and in most cases were not even issued until the 1920's.
Factual error: Henk arrives in Moscow. The KGB gets a copy of his passport. In the next scene, a building can be seen, and a Trabant 601 drives through the shot (one light out). Trabant was East German made and widely exported on the Eastern Block but never to the Soviet Union. This car is definitely wrong there. (00:30:40)
Factual error: At the end the narrator talks of "the Honourable" Winston Churchill. He was actually the Right Honourable.
