Scott Patterson was apprehensive about sticking his head in a sealed box that would fill with water. The trap was tested beforehand and didn't go well, which only added to his concern. He ultimately stepped up and did the scene himself without resorting to a stuntman. The trick to the stunt is that the walls of the box were slid open by stagehands, draining the trap as soon as he signaled with his hands. Several takes were required, however, to capture the scene as he found himself uncomfortable at various points during the shooting of this scene.
Real animal blood was used for the final trap. The director said they wouldn't have used it if they had known how bad it was going to smell.
Danny Glover was offered a chance to reprise his role in a flashback. He had to decline because of shooting conflicts with the film Blindness (2008).
Screenwriters Marcus Dunstan and Patrick Melton briefly appear in the elevator where Hoffman first meets Jigsaw.
