Trivia: Composer Jerskin Fendrix has a cameo as the musician playing the strange instrument in the Lisbon restaurant dance scene.
Trivia: When the film was released, a big deal was made about the fact there's a 10+ year age gap between stars Jennifer Lawrence and Andrew Barth Feldman, with many expressing that they felt it was inappropriate that Lawrence was older. However, the cast and crew pointed out this as being immensely hypocritical, as Bradley Cooper is 15 years older than Lawrence and played her love-interest in "Silver Linings Playbook," which nobody complained about despite her only being only 22 at the time.
Trivia: A teacher at a Miami charter school showed this film to his 4th-grade class. He allowed them to select the film they wanted to watch, and they picked this, with nobody realising it was a horror film. Apparently, the movie played for over 20 minutes before the teacher shut it off, despite earlier protests from his students about its content.
Trivia: Sylvester Stallone originally exited this film in 2017 over creative differences with producer Avi Lerner. Arnold Schwarzenegger exited as well in solidarity with Stallone. The film ended up being shelved for several years until Stallone returned, albeit in a much smaller and final role. Schwarzenegger, as well as other key actors from the franchise, ultimately did not return.
Trivia: The filmmakers wanted to honor the fact that the villains are animatronic robots and decided to use practical effects instead of CGI. The Jim Henson Creature Shop actually built fully-functional animatronic puppets for each character, in addition to suits that could be worn by actors for movements that were too complex for the animatronics to do.
Trivia: The "Prime Video" includes a goof/factual error stating: "At 18:26 when Ben looks in the refrigerator there is definitely light illuminating the interior despite there supposedly being no electricity in the house. In addition, he sets his flashlight on the table so it can't be from that." To the contrary, there is no apparent power outage. Jack leaves Ben a note stating "Keep lights off. Stay hidden" and Ben later flicks off the light switch. The reported "factual error" is nonfactual. (00:04:35 - 00:12:07)
Trivia: The bottom of the alien's ladder looks the same as the part the mechanic puts in Augie's car.
Trivia: Director M. Night Shyamalan has a cameo in the movie, on the television show in the cabin praising an air fryer oven that makes amazing fried chicken.
Trivia: The correct spelling of Kylee Bush is "Tracey", as shown on the "Congratulations" banner at her office and under "Cast" at the end of the movie. Movie-related websites (including IMDb, Rotten Tomatoes, and The Movie Database) apparently receive the same listing for "Cast", which incorrectly spells her name "Tracy". (00:22:30 - 01:26:28)
Trivia: Adam Driver was not allowed to drive any of the historic cars that feature in this movie due to insurance stipulations.
Trivia: Mary is chained outside in the cold and asks Father Munhauser if she can come inside. Father Munhauser replies, "I'll let you sleep in the attic if you can recite for me 'Leviticus Chapter 3'", which she cannot. Leviticus Chapter 3, probably most commonly known as the "Peace Offering," is about 500 words long. (00:01:35)
Trivia: This is the second consecutive Ninja Turtles film in which Rocksteady is portrayed by a professional wrestler. He was played by Sheamus in Teenage Mutant Ninja Turtles: Out of the Shadows, and voiced in this film by John Cena.
