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: 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: 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: 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.
