Jigsaw: Hello, Agent Strahm. If you're hearing this, then you've finally found what you've been looking for. But is the discovery of my body enough? Or will your insatiable hunger to uncover the truth push you deeper into the abyss? Heed my warning: do not proceed. For this room can either be you sanctuary, or it can be your grave. The choice is yours.
Agent Strahm: Fuck you.
The air hoses attached to the glass box at the end of the film are hanging straight down in some shots, and are wrapped around themselves in others, without anybody touching them.
The coffin trap at the end of the movie, in which the walls move in, is based on a drawing done by director David Hackl's young son. (DVD extras)
