The cast were not informed of the identity of the killer until the last day of principal photography. Also, the cast did not receive the last ten pages of the shooting script until it was time to film the scenes contained therein. Furthermore, the last ten pages of the shooting script were printed on gray paper in order to deter illicit duplication of them. All cast members were required to sign confidentiality clauses as parts of their respective contracts that precluded them from discussing the outcome of the story and the killer's identity.
Usually when making a motion picture when an actor is heard on screen, but not seen, such as a voice on a telephone, the actor records his part during post production, which takes place after the completion of principal photography. However, Wes Craven had Roger Jackson, The Voice, on set and actually speaking to on-screen actors by practical, not merely prop, telephone in order to create reality and fear for them. When Jackson was on set he was kept out of sight of other actors so they could not put a friendly face to The Voice. Jackson said that the actors were intimidated by him, and would not talk to him any more than was absolutely necessary, with the exception of Sarah Michelle Gellar, who would converse amiably with him on the telephone between takes.
Kevin Williamson had the idea for a sequel while writing the script for Scream (1996), discovering there was more to the story. Scream 2 (1997) began principal photography just six months after the release of Scream (1996); and it was released less than a year after its predecessor.
In Scream (1996), Tatum asks Sidney, "If they make a movie about you, who's gonna play you?" Sidney answers, "With my luck, they'd cast Tori Spelling." In "Stab," the movie-within-a-movie of Scream 2 (1997), Tori Spelling plays Sidney.
The rules for a horror-movie sequel as stated by Randy are: 1. the death total is always greater; and 2. the murder scenes are always much more elaborate, with more blood and gore. The third rule to surviving a sequel was cut from the movie, but appears in its trailer, "And number three, never, ever under any circumstance assume that the killer is dead."
The plot twists were all a matter of top secrecy throughout production. The screenplay was heavily guarded and restricted to only the most crucial personnel. Certainly none of the cast knew how the film ended as the last 10 pages were withheld from them. Consequently when the first 40 pages of the script were leaked onto the Internet, Kevin Williamson was forced to do some hasty rewrites. This meant that the film went into production without a completed script.
The scene of "Stab," the movie-within-a-movie of Scream 2 (1997), that recreates Casey Becker's death also recreates, and exaggerates, an apparent error of Scream (1996). In Scream (1996) Casey (Drew Barrymore) was stabbed in the chest with an obviously prop, retractable knife, and the wound did not bleed until the shot following the stabbing in which Casey falls to the ground. When Casey (Heather Graham) is stabbed in "Stab," the knife almost leaves her chest, revealing the sweater undamaged.
When Randy and Dewey are talking about the Stab movie, the character of Dewey is played by David Schwimmer, Courtney Cox's on-screen brother in the TV show "Friends" (although Schwimmer does not appear on screen in the part).
The Gothic statues that appear on the college campus are set decorations, not real statutes at the filming location, Agnes Scott. Although the Agnes Scott students on campus during filming were instructed to not tamper with or vandalize the set decorations, and although there was a security guard assigned to the statues, students at least once succeeded in evading the guard and dressing up the statues as a prank.
In the movie trailer and television advertisements for the movie, the scene in which Sidney talks to the killer for the first time on the Lambda house telephone is altered. In the trailers, the killer replies to her question, "It's time, girlfriend!"; and in the theatrical-release version of the movie, the killer says, "I want you. It's show time."
One of two movies to star Laurie Metcalf and feature the song 'Right Place Wrong Time' (performed by The Jon Spencer Blues Explosion in Scream 2 and performed by Dr. John in the 2005 comedy Fun with Dick and Jane).
The trivia items below may give away important plot points.
The play that Sidney is in is Agamemnon, the first in The Oresteia, a trilogy of Ancient Greek tragedies. A running theme in this trilogy is murder and revenge. Clytemnestra kills Agamemnon for sacrificing their daughter and having an affair, and Orestes, their son, seeks revenge for his father's death and mother's affair by killing Clytemnestra, his mother. In this movie, Mrs. Loomis is seeking revenge from Sidney for the death of her son, who killed Sidney's mother for having an affair with his father. The climax of this film about familial murder and revenge plays out on the set of the play about familial murder and revenge.
The 10 deaths in the movie go as follows: Phil Stevens, Maureen Evans, Cici, Randy, Bodyguard 1, Bodyguard 2, Hallie, Derek, Mrs. Loomis (2nd Killer) (it is revealed that she killed Randy), Mickey (1st Killer).
The first draft of the screenplay was titled Sequel to Scream, and it had three different killers than the final draft: Derek, Hallie, and Ms. Loomis. Cotton, after the Killer's reveals, attacked Sidney.
Matthew Lillard who played Stu in Scream is seen in the background at the sorority party that Sidney and Hallie attend (when sisters Lois & Murphy are telling Sidney about the sorority's dedication to promote safe sex). He gives a friendly hug to a guy who has his back to the camera. The guy he is hugging is Mickey who turns out to be the second killer (you see Derek in the background too which indicates that he and Mickey have just arrived at the party after Cici is killed). So you have the second killer from the first film subtly interacting with the second killer in the sequel.
