Factual error: The present day "Grimsby" train station shows electric wires and trains. The real Grimsby only has diesel ones.
Factual error: Jackie is handling medication vials and taking a pill. Some of the vials have childproof "palm and twist" caps, but they were not invented until 1967. (00:48:00 - 00:49:00)
Factual error: The nearest tube station to Wembley Stadium is Wembley Park or Wembley Central and not Park Royal at all.
Factual error: The limo shown is a 1990 (or later) Cadillac. It has large halogen headlamps and not the dual headlamps of a 70-71.
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: 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: Many details are wrong in Elizabeth's execution. The scaffold is in the prison yard, whereas by this time it was inside. The noose has a knot as opposed to the simple slider which was used by this time. Nobody is present except the hangman and one warder, whereas in fact the usual execution party was the prison governor, the chaplain, at least two warders, the hangman and his assistant. The hangman is masked, which never happened in Britain.
Factual error: The open credit sequence takes place at the Atlanta Airport (Hartsfield Jackson), signs are throughout the Delta terminals, Boston Airport announcements are dubbed in until we see John Cusack come off the airplane.
Factual error: Kim is seen using a first generation iPhone in the 2006 scenes. The iPhone was not released until summer 2007.
Factual error: As it happens in many Hollywood movies, we have a gun that is "ceramic" (actually a polymer, "plastic" as Ben corrects himself later) that is entirely stealthy, able to fool the metal detectors at the entrance of a building. It's not an imaginary high-tech device, but is explicitly referenced as the FN Five-seveN handgun (here called repeatedly as FN Five point seven). The metal detector would still pick up the metallic parts and the bullets. (00:40:25)
Factual error: When the boy sends the letter, it already has a postmark.
Factual error: After the death of his beloved pet turtle, Conner is on a downward spiral. One of the headlines that appear as paparazzi follow him (before he gets KTFO'd by Martin Sheen) has a "Friday August 08, 2015" date. Which was a Saturday. (00:58:10)
Factual error: After Calvin logged in a bank account with admin password on his Acer PC at home, he speaks about Chinese bank accounts. But the displayed CH stands for Switzerland. China would be CN. (00:30:30)
Factual error: I'm not 100% on the make of the bolt action rifle Lee is carrying but I know it contains an internal magazine of maximum 5 bullets. She opens the bolt, and no empty shell casing flies out, and for some unknown and stupid reason loads only one round into the chamber. Single shot bolt action rifles are usually very antiquated and hers isn't, or they are very large anti-material rifles with huge calibers of .50 BMG like the Steyr. (01:13:00)
Factual error: Deputy Winston introduces herself and says she's with the Bunyan County Sheriff's Department. Her cruiser is mislabeled with Ackamas County Sheriff markings. (00:57:00)
Factual error: When the characters are drowning on stakes in the ocean there is a modern yacht in the background.
Factual error: When Steve Carell is telling his nephew Jesse Eisenberg that he is leaving his wife, the view from his 1930s era Hollywood Hills home shows the modern skyscraper-filled LA downtown skyline.
Factual error: When Chiron is speaking with the social worker after being assaulted by Kevin, the social worker urges Chiron to press charges. It is the government who decides to press charges, based on evidence gathered by the police, including witness and victim statements. Crime victims do not decide whether or not to press charges. (01:02:20)
Suggested correction: It should be noted the term "press charges" in this case is meant to denote that a victim of a crime reports the crime to the police (as in file a charge against a person to the police), not the legal sense of pressing charges in court. Plus, victims of crimes can pursue a civil case against a criminal.
Factual error: In the Templehoff Airport flyover scene there are Soviet era Antonov An-12 propeller driven aircraft on the tarmac. These were first used by the Soviets in 1953.
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.
