Trivia: Tanedra Howard, who won Scream Queens and got a role in a Saw movie, is featured in the opening trap as Simone.
Trivia: Similar to the previous two films, the writers crafted "Saw VI" to contain subtle parallels and similarities to the original trilogy - in this case most notably "Saw III." These include: -Both films involve the rebellion of Jigsaw's apprentice who has started to become violent/controlling and drift from his methodology. (Amanda/Hoffman) -Both films include a key sequence involving a letter to Amanda. (Amanda discovers the letter in "Saw III", "Saw VI" finally reveals its contents) -Both films involve two separate games going on at the same time involving different people that are revealed to be family in the climax. (In "Saw III", a twist reveals that Jeff and Lynn are husband and wife / In "Saw VI", you discover that William and the imprisoned reporter are siblings during the final act.) -Both films contain a theme of revenge. (Jeff in "Saw III" wanting revenge for his son's accidental death / The family of the man who died due to being refused coverage for a life-saving treatment want revenge on William) -The theme of revenge is acted upon in the final moments of the film. (Jeff kills Jigsaw / The son of the dead man kills William) -Both end with Jigsaw's apprentice being killed/nearly killed. (Amanda dies / Hoffman is severely wounded).
Trivia: Saw 2, Saw 3 and this movie are the only two movies that have an undetermined time between the end of the previous movie and it's beginning. Saw 3, 4 and 5 all occurred over the space of around a week.
Trivia: Reportedly, there was early talk of bringing back Cary Elwes in this film, as Elwes had starred in the original film, but not returned for any prior sequels. While he didn't appear in this film, he did finally return in the following film. Director Kevin Greutert subsequently mentioned that the original plan for Elwes' character in this film would have been greatly different from the direction his character ended up taking in the next.
Chosen answer: The trap wouldn't have worked if William stood on the other side of the cage. When William walks towards the mother and son, you see a closeup of his feet stepping onto a pressure-pad that activates the trap. If William stood on the other side of the cage, the trap would never have turned on because the pressure-pad would not have been set off, and nobody would have died. Also, even though Jigsaw pre-plans his traps, there certainly are circumstances where the mother and son could have gotten hurt. One must remember, Jigsaw is insane, and it's shown repeatedly in the series that even though he intends to help people, he is not above sacrificing people or putting innocent people in harm's way to teach his subjects a lesson. (The most prominent examples being the mother and daughter from the original film and Joyce from "Saw 3D" who were innocent but placed in direct danger to be a motivation for the subjects).
