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: When Sidney is in Olivia's room right after she killed, Sidney is holding onto the very bloody door frame, getting a little on her hands. The next shot when she picks up the phone, seconds later, there is no blood to be seen on her. (00:36:30)
Rachel: A fucking 'Facebook' killer... You're kidding me right?
Chloe: I guess now it would be Twitter, that'd make more sense.
Trivia: While the film is primarily written by "Scream" and "Scream 2" writer Kevin Williamson, due to a hectic production schedule, "Scream 3" writer Ehren Kruger was brought on to do some last-minute rewrites during filming. However, Kruger chose to go uncredited, as he mainly worked on "polishing up" scenes originally written by Williamson.
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.
