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.
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: 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: 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".
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 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: Look closely towards the end of the movie when Randy is explaining the rules look at the videos on top of the TV. One of them is clearly the UK version of the scream video cover under a different name.
