Trivia: There have been rumors ever since the release of "Scream 2" that filmmaker Robert Rodriguez actually directed the scenes from the movie-within-the-movie "Stab." (This would explain why "Scream 4" states that Rodriguez directed "Stab.") However, there are also conflicting reports that director Wes Craven filmed the scenes for "Stab," and even some theories that both directors worked on the "Stab" scenes. To this day, the truth is unclear.
Trivia: Near the beginning of the film when Sidney's roommate goes to the closet we see a red and green (well, blue-ish) striped sweater hanging on the closet door. This is the same style of sweater worn by Freddy Krueger in the Nightmare on Elm Street movies. Two of which were also directed by Wes Craven. Acknowledged also by producer Marianne Maddalena in the DVD commentary track.
Trivia: In one scene, Randy randomly switches to speaking with an English accent for about 30 seconds. Randy's actor Jamie Kennedy has since admitted that he has no clue why he did it... he just did it during one of the takes as a random goof, and was shocked that they kept it in the finished film.
Trivia: Wes Craven has a cameo appearance as a doctor in the hospital.
Trivia: A cameo by Mathew Lillard, at the party at Delta Lambda Zeta house, he is at the back of the screen when Randy says "cocktail".
Trivia: The movie is riddled with side conversations about whether or not a sequel can be as good or better than the original. This is a tongue-in-cheek reference to the movie itself, since people believed that a sequel to "Scream" wouldn't be as funny or successful. However, most people didn't completely 'get' one line when the movie first came out. During the frat party, the second "Star Wars" film is mentioned in this argument, saying that it had better writing. The reply to that was, "Doesn't count; it was not a sequel, it was part of a trilogy." This was once again a reference to Scream 2, since it too was part of a pre-planned trilogy (when Kevin Williamson sent Scream to studios, he also sent along outline scripts for the next two movies).
Trivia: In the scene where Cici Cooper, the sober sister, is watching TV in the house she says to her friend on the phone that Sarah and Bailey broke up - obviously talking about a TV series. She must mean Bailey and Sarah from the series "Party of Five" where Neve Campbell plays a significant role.
Trivia: Joel walks away from Gale leaving the footage he shot. Since his van has been taken as evidence, he has a cab waiting. If you look at the cabbie, who is barely visible, you can see he is wearing a neck brace. That was an improv gag by the extra, who showed up with the brace supposedly as 'protection' against his throat being cut off. Wes Craven enjoyed the idea, much to producer Marianne Maddalena's dismay, but eventually it didn't lead to any extended screentime for the extra. (Anecdote from the DVD commentary). (01:14:05)
Trivia: The script was a major hurdle during production. Because the studio wanted to protect the film's twist ending/killer reveal, most cast members weren't given the ending of the script until the day they filmed the twist ending/killer reveal scene. Part of the script was also leaked online, and thus those pages had to be rewritten on the fly so people wouldn't be able to guess the plot.
Trivia: While a majority of the music is composed by Marco Beltrami, Dewey's musical theme is actually a piece from the 1996 action movie "Broken Arrow." It was used as a temp-track while editing and was intended to be replaced... but everyone working on the film fell in love with it since it seemed to perfectly sum up Dewey. The studio ended up licensing the music for use. Famed composer Danny Elfman also assisted by composing a piece of music for the scene where Sidney is in a play.
Trivia: When Cici and her friend are talking on the phone about 'Party of Five',they are insulting the character of Sarah and commenting "That girl needs to get her shit together". These lines were written for Jennifer Love Hewitt, who plays Sarah Reeves and was originally supposed to play Cici, and weren't changed when Sarah Michelle Gellar was brought in instead.
Trivia: The shoot happened to coincide with the shoot for season four of "Party of Five," which also starred Neve Campbell. Because she had to film both simultaneously, and both had day and night shoots, she was working seven days a week, and often didn't have time to sleep... she'd go from one shoot right to the next, then hopefully be able to sleep after that.
Trivia: During the theater play scene, one of the film technicians in charge of the fake smoke nearly got asphyxiated working with the dry-ice in the enclosed space of the orchestra pit as he lost the mask he needed to breathe. The incident caused a turmoil on set with everyone rushing to help him, and an ambulance was needed, but everyone ultimately was fine. Anecdote narrated by Wes Craven in the DVD commentary track.
Trivia: SPOILER: There's a "blink and you'll miss it" clue to one of the killer's identities. When they discover Randy's body, there's a quick shot of his bloody hand. Among the smears of blood, you can also very briefly see a distinct red lipstick mark on his hand. It's similar to the lipstick shade Debbie Salt wears in a few scenes. Debbie is later revealed to be one of the killers, and mentions that she killed Randy. (Presumably he got her lipstick on his hand while they were struggling).
