Stupidity: Jill wasn't thinking too clearly when she plans her story. She only wiped the fingerprints off the gun but they would be all over the tape on Trevor's body. Then she wipes off the knife yet touches it again to slide it across the floor. She was thinking that Trevor and Charlie were going to be thought of as the killers but their fingerprints weren't on either of the weapons.
Scream 4 (2011)
2 stupidities
Directed by: Wes Craven
Starring: Courteney Cox, David Arquette, Neve Campbell, Lucy Hale
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)
Sheriff Dewey Riley: One generation's tragedy is the next one's joke.
Trivia: When Deputy Perkins is pretending to be dead in the squad car, Deputy Hoss reveals Perkins' first name to be "Anthony". Anthony Perkins was the name of the actor who played Norman Bates, the killer in the original "Psycho".
Question: In the final shot, we see Jill's head move a little. Was that suppose to let the viewers know that she's alive or was it just a mistake?
Answer: I actually read that they noticed this before the movie came out and left it in to keep the ending ambiguous and since they were planning to make Scream 5, they felt that would possibly be the way to go.
That's very interesting, especially now that Scream 5 is finally getting made. Although it doesn't appear that Emma Roberts is returning.
Answer: I personally submitted this as a revealing mistake. There is no official statement from Wes Craven or anyone else involved in the making of the movie about it being deliberate. So in my eyes, it's a mistake.
