Trivia: The film is edited by Kevin Greutert, who edited "Saw" 1-5, and directed the sixth and seventh films. Greutert is one of only a few holdover crewmembers from the original run of the series to return. He said he felt an obligation to be a part of "Jigsaw"- feeling that given his past with the series, he should help usher the franchise into the new direction that the producers and writers wanted to take, while also helping to maintain ties to what came before.
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: During production, rumors swirled that the film would be a "light reboot" that would only acknowledge the events of "Saw" I-III, while ignoring IV-VII. However, the film does contain several minor allusions to the later sequels, and co-writer Josh Stolberg later confirmed that the film does indeed follow all seven original films, even if it doesn't directly reference them.
Trivia: Major Spoilers: At the end of the film, pathologist Logan Nelson is revealed to be an apprentice of Jigsaw. Big fans of the series might have noticed on a second viewing that his character was very subtly alluded to being an apprentice, as he shares many common or similar traits with other secret apprentices in the series. Logan has a young daughter, just as Lawrence Gordon had a young daughter. Logan had taken part in a game and survived (albeit accidentally) as revealed in the end, just as Amanda Young had survived a test before joining Jigsaw. And Logan had lost someone close to him that served as a personal motivation (his wife), just as Mark Hoffman had lost his sister, which started him down the path towards becoming an apprentice.
Trivia: "Jigsaw" is the only "Saw" film to not get an "unrated" or "extended" version released on home video, with only the original R-rated theatrical version having been announced for home video. Additionally, "Jigsaw" is the first "Saw" film to be released on the 4K Super-HD format, in addition to a standard Blu-Ray and DVD release.
Trivia: A rather complex scene was filmed in which Eleanor trapped Logan in her reproduction of the motorcycle trap in her workshop, only for it to be revealed the blades were made of rubber and completely harmless, but the scene was cut for being a bit too long, and because it was felt the sequence undermined the later scene where we see the real version of the trap being used. Despite the scene having been deleted, the producers confirmed it was one of the most complex scenes ever filmed for the series due to the limitations of the set and the complicated camera moves. They were also somewhat annoyed it had to be cut due to the time and effort spent on it.
Trivia: Minor Spoilers. When Eleanor reveals her "workshop" and shows Logan the "trap" reproductions she's created, among those that are visible are: the "Reverse Bear Trap" from the original "Saw", the "Magnum Eyehole" from "Saw II", the "Angel" Trap from "Saw III", and the "Head Cube" from "Saw V." Other traps are also visible in the background.
Trivia: Spoilers. There's a major clue in the film that hints at the ending twist that the barn game takes place in the distant past. In every other "Saw" sequel, the characters in tests repeatedly acknowledge and discuss the fact that Jigsaw is a known criminal, and discuss how to beat their games. (Or alternately are people who directly knew him.) In "Jigsaw", none of the characters in the barn acknowledge that they are in a Jigsaw game (since he wouldn't be known yet to the police or press), and the only references to Jigsaw take place during the scenes set in the present.TedStixon
Trivia: The writers got the idea for the motorcycle/spiral-blade trap from a counter-top veggie "spiralizer"- a kitchen tool that slices veggies into thin "noodles." They thought it would be a wild idea for a trap to have someone fed into a blade that would slice up their body in a similar fashion.
Trivia: Co-Writer Josh Stolberg confirmed in an interview that the original climax trap scene was vastly different, and that while it lead to the same outcome (Halloran dying and Logan being revealed to be a secret accomplice of Jigsaw), it was significantly longer and significantly gorier. However, he ultimately agreed that due to the intimate nature of the climax, it was better to go with a simpler, faster trap that put the focus on the characters moreso than the gore.
