Trivia: Patrick Melton and Marcus Dunstan, the writers of both "Saw IV" and "Saw V", have a cameo in the flashback of Hoffman being kidnapped and meeting Jigsaw for the first time. When Hoffman is about to get on the elevator right before getting kidnapped, Dunstan is the second man to exit the elevator (he is in black and has a beard), right after the snobbish woman. Melton is the tall man who exits the elevator last before Hoffman enters.

Trivia: At one point, Strahm's head-trap was going to be featured at the end of "Saw IV", but it was eventually decided by the filmmakers that the trap was strong enough that it could be one of the featured traps in "Saw V."

Trivia: The elderly couple who notices Jill Tuck in the waiting room near the beginning are actually the parents of the film's casting director, and the receptionist in the scene is played by a receptionist who works for Twisted Pictures (which produces the "Saw" films) in real life.
