10 Horror Movie Villains Who Went To Great Lengths

Saw's primary antagonist, Jigsaw - aka John Kramer - might be the most single-minded dead-man-walking in cinema. Despite being elderly and battling terminal brain cancer, Kramer is determined to perform deadly trials on his victims.

For these tests, Jigsaw needs to build dozens of elaborate booby traps, and even though he's a master engineer, performing these tasks requires a staggering amount of time, effort, and money. Added to that, John has to scout for abandoned buildings and create a myriad of recordings to instruct his unwilling contestants how to survive, plus construct a marionette puppet to move on a toy tricycle for certain challenges because... reasons.
