Trivia: The school scenes were originally meant to be filmed in the Santa Rosa High School. However, right before filming began, the school officials pulled out of the project. The crew was forced to scramble to find another school at the last second. Director Wes Craven was furious at the school board, and decided to poke some fun at them in the credits. If you wait around long enough, you'll see the message "No thanks whatsoever to the Santa Rosa City School District Governing Board."
Trivia: When Sidney and Tatum are talking on the porch, Sidney says, "...If I'm wrong, that means the killer may still be out there..." Tatum replies, "Don't go there, Sid. You're starting to sound like some Wes Carpenter flick." This is an inside joke about "Scream" director Wes Craven. He often jokes about how people always confuse him with "Halloween" director John Carpenter. (00:54:10)
Trivia: The murder of Principal Himbry was added after producer Bob Weinstein noticed there were about thirty pages in the script (which roughly translates to thirty minutes of screen time) in which nobody died. The scene also resolved the climax at Stu's party, as it gave all the guests a reason to leave.
Trivia: In the beginning when Casey's parents come and hear her choking on the phone, Casey's dad says "Listen, I want you to drive to the MacKenzie's house and call the police." At the end of the movie Halloween, Laurie Strode tells the two little kids she's babysitting to walk over to the MacKenzie's house to call the police.
Trivia: Casey says about the "Nightmare on Elm Street" films that "the first one was scary but the rest sucked." The first film was directed by Wes Craven, the sequels weren't. He did direct "New Nightmare", but it doesn't really count as a) it's not called "A Nightmare on Elm Street" and b) is set outside the continuity of the other films, classing them all just as films compared to the "reality" of itself. Alternatively of course she's just mistaken.
Trivia: The killer's costume in the Scream movies has come to be known as "Ghostface". When the costume's package is first shown to the Police Chief by Dewey, it is actually called "Father Death". The only time "Ghostface" is actually mentioned is by Tatum right before she dies, when she calls him "Mr. Ghostface". (00:35:05 - 01:06:15)
Trivia: In the beginning of the film before Drew Barrymore is killed, Wes Craven needed to make sure she was as upset as possible for the scenes that followed. As Drew is a huge animal lover Wes kept reminding her of an incident where an animal had been hurt by a human which then led to her getting upset.
Trivia: Ghostface is mainly played by a stuntman, not the two actors he is portrayed to be.
