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 movie puts a caption in the prologue "January 2013." Later the protagonist puts the hammer he received by the mysterious delivery right on top of a newspaper, a copy of "Mid-Day" with a retouched opening article (related to the movie murder of course) but headline news with a Sunil Gavaskar quote that dates it as a December 2015 edition. (00:03:20 - 00:10:10)
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: 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: 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: The email Vee gets at the start is dated 2017, and calls for her to become part of the class of 2020. If she went to CalArts in September of 2017, she would be part of the class of 2021. (00:01:05)
Factual error: When the characters are drowning on stakes in the ocean there is a modern yacht in the background.
Factual error: The girls are looking through a rather wide gap between the door and the door-sill. If a gap were that wide the door lock would not be very secure, and just a little force would open it. (00:19:25)
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: The 5th Amendment to the Constitution simply states that "No person... shall be compelled in any criminal case to be a witness against himself." There is no actual or implied provision that means once you have answered a question, you can't plead the 5th on any subsequent questions, as the movie depicts.
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: For the third movie in a row -at least they are consistent - Maggie introduces herself as Detective of the SFPD, but detectives are not referred as such, but as Inspectors.
Factual error: When Joe and his girlfriend, who is also Albert White's mistress, walk through the hotel room kitchen, that whole kitchen, is not a 30's era kitchen. It even has a convection oven and a blast chiller, pan racks, etc. that are more from this time.
Factual error: In the scene when they are locked in the garage, they attempt to use vehicle air bags to propel themselves through a garage vent in the roof. It is absolutely impossible for a air bag to deploy by jumping on it. A air bag requires specific battery voltage and resistance supplied by a air bag control module to deploy a air bag. The physical act of jumping on it will not deploy it.
Factual error: Tommy states that Jimson Weed is a paralytic, but it is not known to have this property. It is however a powerful hallucinogen and deliriant.
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: When Pete is riding on the back of the school bus and jumping on top of the bus in the background a New Zealand style Give Way sign is seen and also on the left hand side of the road. The film is set in the USA so this should have been on the right hand side of the road. (00:34:00)
Factual error: A bullhorn can be heard in the background off-screen during a battle with the zombies, even though the movie takes place during Victorian times. (01:19:30)
Factual error: In the wedding scene and after the arrests, the U.S. Customs Service officials in uniform with the canines have two Customs patches on their jackets dating from the late 90s. In the 1980s and 1990s the Customs Service uniforms had only one patch on the left sleeve. (01:58:00)
