Trivia: Director Kevin Greutert has stated that the film was made with the intention of it being Tobin Bell's swan-song in the role of Jigsaw, and a proper send-off for the character, though he stressed "never say never" when asked about a sequel or Bell possibly returning in the future.
Trivia: Director Kevin Greutert is one of the only crew members to be directly involved with all ten movies. He edited "Saw" 1-5 and "Jigsaw," directed "Saw VI," "Saw 3D," and "Saw X," and was an executive producer on "Spiral: From the Book of Saw."
Trivia: An assistant editor was working on a cut of the "Eye Vacuum" trap one day when the doorbell rang. He was shocked to find police at the door. Turns out, someone in a neighbouring building overheard the edit and misinterpreted the screams in the footage as someone actually being tortured to death, so they called the cops. The officers were very amused when they found out he was just editing a movie. Director Kevin Greutert later joked, "It must have been a pretty realistic performance!"
Trivia: The writers were reportedly began working on this film not too long after the release of "Jigsaw" in 2017. However, Chris Rock's project "Spiral: From the Book of Saw" became a priority, and this project was placed on hold. When that film failed to live up to previous entries at the box office, the producers allowed the writers to bring this project back and try to course-correct the series.
Trivia: Minor spoilers: The first movie in the series in which the film continues after the classic theme "Hello Zepp" plays. In every other movie, the song signals the ending of the film, and the song concludes with a cut to black. Whereas, in this movie, there's an additional scene before the credits start.
Trivia: Stay tuned after the credits start. Midway through, there is a bonus scene showing a loose end from earlier in the film being tied up, in addition to a cameo from a legacy character. This scene also makes "Saw X" the first theatrical "Saw" film to feature a credits scene. (While the unrated cut of "Saw VI" had a credits scene, it was only on DVD and Blu-Ray and never shown in theaters.)
Trivia: To honor this being the tenth film in the franchise, Lionsgate allowed the production to use the old "turning gears" logo that was used in the original seven films, before it was phased out for their newer, more modern logo that was seen in "Jigsaw" and "Spiral: From the Book of Saw."
Trivia: As part of the film's marketing, the studio made a spoof of AMC Theaters' "We Come to This Place" commercial that plays just before films in their theaters start, with Billy the Puppet in place of Nicole Kidman. In response, AMC's CEO, Adam Aron, actually asked Lionsgate to pull the ad, to which the latter obliged.
Trivia: Just something amusing to pay attention to... during the "Eye Trap," Jigsaw gives the subject a 60-second time limit. But if you actually time the scene, the trap goes off only about 55 seconds after it starts. This is actually quite ironic because in the other movies, a common error is that the trap scenes last way longer than the time limits Jigsaw gives, whereas this one is actually slightly shorter. (Probably not a mistake, however, since it's a "vision" and not real.)
Answer: If I'm not mistaken, the room she was in was locked. She may have been able to survive the trap by sticking her head through the opening, but if she has no way of leaving the room, eventually she would starve to death.
