20 Things You Somehow Missed In Scream
15. The "Two Killers" Twist Is Foreshadowed
Beyond the identity of the killer(s) being revealed, Scream's big twist is that there's not one but two culprits running around as Ghostface - Billy and Stu Macher (Matthew Lillard).
This shock reveal is also slyly foreshadowed half-way through the movie when Principal Himbry (Henry Winkler) chews out two students who played a prank dressed as Ghostface.
It's obviously missed by just about everyone on their first viewing, but when watched within the context of the entire film itself on a repeat viewing, it's clearly a cheeky wink to in-the-know fans.
