Factual error: When Eakins returns to the house after he swears an oath to the union. You can see a thermostat on the wall behind him. (01:40:00)
Factual error: Women's stockings had seams in 1944. When people are dancing at the party in Bayfield's apartment, the backs of women's legs appear in enough shots to show that their stockings, anachronistically, are seamless.
Factual error: Once the men first climb up to "Hacksaw Ridge," the camera pans over numerous corpses. One of them has an M1 Helmet lying on its top to where the liner is seen. The liner has the web suspension straps cross each other instead of being tied in the center. This means the liner is a Vietnam era type, and not World War II.
Factual error: When Vinny Panzienza has his cervical halo brace removed (without anesthetics), he yells and groans and grunts in pain, but his hands are relaxed on the arms of the chair. I can tell you, from experience with this exact situation, the pain is so intense that his hands should have been clenched as tight as a vise.
Factual error: There would be no room for a thumb drive inside of a real Rubik's Cube due to the way they are constructed. When dismantled, the individual moving parts are quite small. It would certainly be possible to construct a facsimile of a Rubik's Cube that would have enough room, but it wouldn't be a fully functional puzzle the way it was in the film.
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: James is playing his guitar outside a station. Before the frontal shot that identifies it as Covent Garden, there's a street poster for the musical version of "Matilda." The play was already in existence in the movie timeframe, but the poster is in its "Believe the hype" version that is post 2013. The movie ends in 2012. (00:19:55)
