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: While Guy fights with Dude, there is kid with a red shirt watching the game. Behind his back there is a Deadpool poster, another Ryan Reynolds movie.
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: This is the third film in the X-Men franchise to make reference to the villain Mr. Sinister, following X-Men: Apocalypse and Deadpool 2, by way of the Essex Corporation (Nathaniel Essex being Mr. Sinister's real name). The logo for the Essex Corporation is a diamond, similar to the ones Mr. Sinister has on his forehead and chest in the comics. Unfortunately, since this is the final film in the Fox X-Men franchise, Mr. Sinister himself never made a physical appearance in any of the films.
Trivia: Thea is played by Samara Weaving, niece of Hugo Weaving. The elder Weaving notably co-starred with Keanu Reeves in the "Matrix" trilogy.
Trivia: Dylan's mom's story about the Florida man who was in bed when a sinkhole opened up under him actually happened to Jeffrey Bush on 2/28/13 in Seffner, Fl (Tampa suburb). He (along with his bedroom furniture) was entombed. Brother Jeremy heard him scream, jumped in with a shovel and tried to dig him out, but Jeffrey's body was never recovered. The house was razed and the sinkhole filled in but it re-opened 2+ years later on 8/20/15. Sinkholes are common in FL and 6 states - AL, KY, MS, PA, TN, TX. (01:26:35)
Trivia: Originally, John Krasinski didn't want to write or direct the film. He came up with the basic story, but intended to hand off the project to another writer/director to develop and helm. However, the studio was eventually able to convince him to return.
