10 Movie Reveals You Can Spot Early (If You Really Look)
5. John Kramer Is Jigsaw - Saw
The Reveal
The Jigsaw Killer is none other than John Kramer (Tobin Bell), the cancer patient we see Dr. Gordon (Cary Elwes) briefly encounter while doing the hospital rounds with his patients in an early flashback.
How To Spot It Early
Those who take a cursory glance over at John's bedside table will see a most curious sketch: he's been drawing what is very clearly the reverse-bear trap.
No more than five minutes later, we see Amanda (Shawnee Smith) locked into this very trap, and so for anyone paying sufficient attention, it's clear as day that this seemingly random character is actually either Jigsaw himself or one of his apprentices.
As it pertains to Kramer's whole "pretending to be dead in the middle of the bathroom" act, there's also a pretty clear hint that he's still alive.
When the gun he used to allegedly shoot himself in the head is opened up later, the cylinder doesn't contain any spent casings, making it impossible for any bullet to have been fired. Sloppy work, John.
