Continuity mistake: In the scene where Jill and Charlie are revealed as the killers, Jill is holding a knife to Sidney's throat and a gun in her left hand as she explains her motive. When Jill and Charlie are getting ready to stab each other, the shot changes and Charlie hands Jill the knife, even though she just had it in her hand pointing it at Sidney. (01:11:20)

Starring: Courteney Cox, David Arquette, Neve Campbell, Lucy Hale
Jill and Charlie are the killers. Jill kills Charlie with the intent of framing him for the murders and making it look like Jill is the hero, just like Sidney was. Jill stabs Sidney to keep her quiet and then makes it look like Charlie killed Sidney and Jill saved the day. Jill is taken to the hospital, but finds out that Sidney survived. She tries to kill Sidney, who eventually electrocutes her and shoots her. But the media reports that Jill is a hero, meaning that she got what she wanted.

Question: When Jill and Kirby were watching "Shaun of the Dead", and Ghostface calls them, how did he know they were watching that?
Answer: Also, pretty sure they told Olivia over the phone what they were watching and Ghostface was in the closet listening.
Answer: Remember that Jill and Charlie were the killers and were working together. Therefore, Jill probably told Charlie the film they were planning on watching. Meaning when he called Kirby he knew what she and Jill were watching, which makes the killer more sinister and omnipresent.
