Saw | Saw II | Saw III | Saw IV | Saw V | Saw VI | Saw 3D | Jigsaw | Spiral | Saw X
- Absurdly Short Production Time: Saw IV had the shortest filming time in the series thus far, at 17 days (though it's a narrow margin when compared to the second-shortest, the first film's 18 days).
- Enforced Method Acting: Apparently, in the scene where Hoffman views Jigsaw's body at his autopsy, Costas Mandylor really thought it was Tobin Bell instead of a lifelike dummy and was mortified, even asking for him to be covered up.
- Refitted for Sequel: The Knife Chair was made out of a similar trap conceptualized for Saw IInote , which involved a waffle grill instead of the former trap's knife mechanism.
