Trivia: This is the first film in the Saw franchise in which Tobin Bell does not appear in any new scenes. He only appears in photographs during the investigation.
Trivia: When Zeke and William are scoping out the meth house, Zeke remarks "This is some New Jack City shit." Chris Rock, who plays Zeke, also appeared in New Jack City, playing a police informant inside a crack house.
Trivia: Chris Rock is reportedly a big fan of the "Saw" film series, and came up with the basic story for the film, which he pitched to Lionsgate. Lionsgate loved his new take on the series, and not only let Rock star in the film, but also made him an executive producer on the project.
