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 plot of the movie is similar to Groundhog Day which is something that Carter mentions to Tree at the end of the movie. Tree's roommate's name is Laurie Spengler, which is a reference to Egon Spengler, played by Harold Ramis in Ghostbusters. Harold Ramis co-wrote and directed Groundhog Day.
