Trivia: The producers have stated that "Jigsaw" was created as they wanted to bring the "Saw" series back, and they wanted to gauge audience interest in more films. When the film became a hit - earning about $100 million worldwide against a relatively tiny $10 million budget - a ninth film was announced, with a tenth also possible.
Trivia: When Roy McBride is reviewing a top-secret message regarding his father and the LIMA mission, the message filename is "6EQUJ5," which is a very obscure easter egg in the movie. The filename 6EQUJ5 refers to the real-life "WOW Signal," a deep space radio signal received by the Big Ear radio telescope at Ohio State University in 1977. The alpha-numeric designation "6EQUJ5" was a printed readout of the signal's duration and intensity. This signal lasted 72 seconds and was 20 times stronger than background radio noise, causing a surprised astronomer to circle the printed 6EQUJ5 readout in red ink and make the handwritten notation "WOW!" in the margin. While the signal was an anomalous one-time event that was never repeated, and there is still no proof that 6EQUJ5 was alien in origin, it has stimulated debate about extraterrestrial radio signals for decades. Ironically, the movie "Ad Astra" concludes that there are no alien radio signals and that we really are alone in the universe.
Trivia: The directorial debut of series co-star Patrick Wilson.
Trivia: While filming the movie "Dumb And Dumber Too", Jim Carrey admitted to Jeff Daniels that he hated making this movie because he found it an offensive depiction of the native people, and he never understood why Ace, who was a lover of all animals, was afraid of bats.

Trivia: The family of late author Roald Dahl who wrote the novel The Witches gave director Robert Zemeckis permission to do a remake on the condition that the ending of the movie follow the ending of the book, where the boy remains a mouse.
Trivia: When the kids are walking down the stairs in the subway station, you can see one guy walking upstairs dressed as the character Mojo Jojo from "The Powerpuff Girls." Mojo Jojo was voiced by Roger L. Jackson, the same voice actor for Ghostface.
Trivia: During Joey's nightmare, he is seduced by a topless nurse who then captures him before turning into Freddy. As originally conceived, only her face was going to transform at first, thus having Freddy's burnt male head on top of an otherwise perfect topless female body in order to create an eerie, otherworldly look. The actress portraying the nurse even took part in some test shots and performed the scene under heavy prosthetics to make her face look exactly like Freddy's. However, the effect was cut as the crew felt it looked far too weird, and that it diminished the moment when Freddy fully appears on-camera in the scene.
Trivia: Jimmy didn't die even though it never shows him after he faints on the steering wheel in the car with Lori. He simply passed out. The television cut shows him alive in the ambulance at the end, but for some reason in the theatrical version, they left it out for us to 'wonder'.
Trivia: At the very end of the movie when the new kids are telling the story, they make a sarcastic comment about the killer being the girl from the Noxzema commercials. The girl who played the killer, Rebecca Gayheart, really was the girl from the Noxzema commercials.
Trivia: Like Tanedra Howard won a role in Saw 6, Gabby West won the second season of Scream Queens and is featured in this film. She is Kara, Evan's girlfriend. She is underneath one of the rear wheels of the car in the garage trap.

Trivia: In the hospital Heather is told that she can not be in a certain area without a pass; she replies "Screw your pass." The very same line was spoken, by her character Nancy in Nightmare on Elm Street 1, to a hall monitor in her dream.
