Trivia: Director Jason Reitman is the son of Ivan Reitman, director of the original "Ghostbusters" and "Ghostbusters II." As a child, Jason actually had a cameo in "Ghostbusters II" during the birthday party in the beginning. (He's the kid who tells Ray he heard the Ghostbusters were "full of crap").
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: This is the sequel to "After" (2019).
Suggested correction: This isn't trivia, especially since it stars the main cast of characters and is based on the sequel to the book.
Arguably, EVERYTHING is trivia.
No, anything obvious, common knowledge, or easily seen by viewers is NOT trivia. Also, things unrelated to the film or those involved is not trivia.
The "easily seen by viewers" is a bit of a grey area, because people (well, I) do read trivia listings before seeing a movie just for background info. But I agree that not everything can be trivia - it needs to be broadly of note, although granted that's highly subjective!
Trivia: Felix ordered a "Cutty on the rocks" at the restaurant. "Cutty Sark" is a Scotch whisky ("whiskey" in the U.S. and Ireland), meaning it must be manufactured in Scotland. Mobsters (not meant to be referring to Felix) are known for ordering drinks by brand name, such as "Cutty on the rocks", but not "Scotch on the rocks." During U.S. prohibition (1920 - 1933), Cutty Sark became well-known as a bootlegged (illegally trafficked) liquor. (00:20:35)
Trivia: The "Sea Star," the boat that the alien takes to the island, is also the name of Donald Sutherland's tugboat in the sci fi movie "Virus," a movie about electronic alien invaders.

Trivia: Dave Franco was a co-writer and (first-time) director of this movie. Dave's real-life wife, Alison Brie, starred as "Michelle." Alison (38) is about 2.5 years older than Dave (35).
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.
