Trivia: Kevin Williamson (who had written the first two films, as well as the fourth) had an entirely different plot in mind, which he had outlined and given to the studio, only for it to be passed on. His original concept had the killers in the film be members of a "Stab" (the film-within-the-film) fan-club, who orchestrated the murders in order to gain fame and become heirs to Sidney Prescott's status as the soul-survivor. Aspects of this unused original story treatment were re-written into the fourth film, which features a killer whose motivation is fame and becoming the soul-survivor.
Trivia: Matthew Lillard revealed that his character from the first film, Ghostface killer Stuart "Stu" Macher, was originally going to be the new Ghostface killer in this film. Stu actually survived when Sidney pushed the TV on his head. From prison, Stu was going to orchestrate new Ghostface attacks to get revenge on Sidney. Stu was ultimately written out of the film and replaced with Roman Bridger.
Trivia: At one point, it was not known whether Neve Campbell would be able to appear in the film as Sidney due to her hectic work schedule. The studio even considered writing out of the character. She eventually agreed to appear in the film, but was only able to be on-set for a few weeks. This is why she doesn't have as many scenes as she does in the other three "Scream" movies.
