10 Horror Movie Characters You Trusted (But Shouldn't Have)

Given that the third Scream movie literally had the Ghostface killer be Sidney's (Neve Campbell) half-brother Roman (Scott Foley), fans probably should've put Sid's cousin, Jill Roberts (Emma Roberts), under some additional scrutiny in Scream 4.

But with pre-release rumours indicating that Scream 4 was set to be a soft reboot of-sorts for the franchise, it was easy to believe that Jill - who, frankly, had Final Girl written all over her - would basically be "the new Sidney."

And so, suspicion was quite ingeniously cast away from her towards a glut of more likely suspects, only for the third act to reveal that, indeed, Jill was one of the film's two Ghostface killers - and the primary one, no less.

It's a credit to Emma Roberts' performance that she's absolutely persuasive as both the vulnerable, pre-reveal Jill and her psychopathic, post-unmasking true self, and that the two "sides" of the character still feel of-a-piece with one another.

All the same, after Scream 3 flat-out told us not to take Sid's relatives at face value, we should've known better than to trust that Jill wouldn't get stab-happy.
