Trivia: The Sator Square dates back to Pompeii and is a square of 5 Latin words making a palindrome: Sator, Arepo, Tenet, Opera, and Rotas. Whichever orientation the square is in the words line up in both directions. Each word features in the film - Kenneth Branagh's character is named Sator, the forger mentioned near the start is Arepo, the title is of course Tenet, the opening sequence takes place in an Opera, and the Ukranian special forces who arrive in that sequence have badges on their arms with "Rotas" on them.
Trivia: As the family is leaving home in their car, a neighbor asks that they also take her daughter, Ellie. ELE, pronounced the same as the name, stands for Extinction Level Event.
Trivia: Will Smith dismisses the new task force "AMMO" as "a high school musical boyband with guns." AMMO member Kelly is played by Vanessa Hudgens, who starred in the High School Musical franchise.
Trivia: The original title was "Freaky Friday the 13th," but it was shortened to "Freaky."
Trivia: Officer John Marshall has fangs, but they aren't particularly noticeable. (00:22:01)
Trivia: Despite his prominent billing, John Krasinski has less than 10 minutes of screen time in the entire film (all in flashbacks), due to his character's death in the first film.
Trivia: Many people are familiar with the "Stockholm Syndrome" wherein hostages or kidnapping victims develop a connection with their offenders - they identify with or feel empathy for the people holding them captive. The "Stockholm Syndrome" is also known as "capture bonding." Its lesser-known opposite (or inverse) is called the "Lima Syndrome" - the hostage-takers or kidnappers start identifying with or "feeling for" their victims; they bond. This movie portrays BOTH, but with a different crime.
Trivia: "Aggressive driving" and "Road Rage" are not the same thing, but there is some overlap: Not all aggressive driving is road rage, but road rage is an extreme form of aggressive driving. In general, aggressive driving (such as tailgating) is classified as a traffic offense or summary offense (typically punishable by a fine but can result in suspension of driver's license and possibly include a short jail sentence) whereas road rage is classified as a criminal offense (and also falls under civil offenses or torts) because the intent is to cause harm. Road rage can take the form of an aggravated assault by vehicle (felony offense); less serious incidents are sometimes written up as "reckless driving", lowering the classification to a summary (traffic) offense. When a driver becomes angry, wants to cause harm to another person/driver, and a person is injured, the driver's behavior is deemed violent and subject to criminal prosecution as a felony offense.
Trivia: The "Deception" bottle in the movie has been altered. "Honey Flavored Whiskey" (not just "Whiskey") should be written below "Deception." The movie version bottle also has Tennessee on it, but "Deception" is from Texas. A 750 ml bottle typically costs between $30 - $40 and is 40% ABC or 80 Proof. Some people refer to "Deception" as "Deception and vibe." (00:35:25)
Trivia: There are several subtle references to the 2018 film "Searching" in this movie. Most notably, the stock-photo model Hannah from "Searching" is briefly seen in this film in a thumbnail image for a YouTube video. Director Aneesh Chaganty has stated that this was intentional, and that "Searching," "Run" and by extension, "Missing" (the semi-sequel to "Searching") are all set within the same cinematic universe.
