Trope-based trivia:
- Absurdly Short Production Time: It took 42 days to shoot the film.
- Acting in the Dark: When Scott Patterson signed on, it was for three films, and his character was supposed to survive this film and appear in the next. When the ending was changed to Strahm being killed off, Patterson wasn't informed, and didn't know the ending had been changed until the SFX team came to do casts of his arms to be used for the bone-breaking sequence at the end of the film. When he asked during the process what the arm casts were for, the SFX person, surprised that he didn't know, was the one who told Patterson that his character was being killed off.
- Descended Creator: The people who leave the elevator that Hoffman goes to were played by several of the film's writers and producers.
- Dueling Works: Opened the same weekend as High School Musical 3: Senior Year and because of that movie, was the first Saw sequel to not open at number one.
- Inspiration for the Work: According to David Hackl, the idea for the closing walls in the Glass Coffin's room at the end of the film came from his then-9-year-old son.note He took the idea because he actually wanted to have an actual The Walls Are Closing In scene where the character doesn't escape the room in time and instead gets crushed.note
- No Stunt Double: For the Water Cube, Scott Patterson's head was actually locked in a glass cube that can be filled with water, albeit one with two accessible doors. He had hand signs so that when he couldn't continue holding his breath, crew members could quickly run in and drain the water. It was even said that the trap had to have Patterson instead of a stunt double out of realism for the scene.
- Refitted for Sequel: In the home video extra "The Making of the Cube Trap", Patrick Melton mentions that the Water Cube was initially written for use in Saw IV before being moved to this film for being deemed better in it.
Miscellaneous trivia:
- During filming, David Hackl's office for the film's production was drastically modified and used as the set for Hoffman's office. As a matter of fact, the hallway Hoffman walks into led to the production studio, and the background people present weren't cast members at all.
