10 Horror Movies Where NOBODY Guessed The Killer

10. Roman Bridger - Scream 3

Scream 3 may be the consensus-worst entry into the franchise, but it still delivers a genuinely jolting killer reveal, when we find out that, for the first time in the series, Ghostface is a solo operator - and more to the point, it's Stab 3 director Roman Bridger (Scott Foley).

There are two reasons why most fans didn't pin the murders on Roman - first off, who could've ever anticipated that Roman would actually be Sidney Prescott's (Neve Campbell) secret half-brother, born to her mother Maureen? Holy retcon, Batman.

And secondly, there's the fact that Roman fakes his death earlier in the movie in a manner so persuasive as to steer all suspicion away from him. 

Gale (Courteney Cox) discovers his "corpse" inside a prop coffin covered in blood with a knife protruding from his chest, and even checks his pulse to confirm that, yes, he's no more.

Except, Roman inexplicably reappears later to reveal that he was the Bad Guy all along - a reveal that's unpredictable precisely because the movie makes it near-impossible to guess through its sheer implausibility.

It's never explained how Roman could exist without a pulse, but there are a few deeply silly options here - he either took a sedative to slow his heart rate down to near-death, used an extremely convincing prop of his own dead body, or Gale simply couldn't find his pulse in her panic.

It's some of the flimsiest writing in any of the Scream movies, but at least served its contrived purpose in preventing fans from figuring out that Roman was the killer.
