Scream is a 1996 horror film directed by Wes Craven from a screenplay by Kevin Williamson, and the first of the Scream series. Filmed mostly in Santa Rosa, California, the film tells the story of the fictional town Woodsboro, California being terrorized by a masked killer who enjoys tormenting his victims with phone calls and movie references. The killer's main target is Sidney Prescott (Neve Campbell), a teenage girl whose mother Maureen fell victim to a brutal murder one year earlier. The film takes on a "whodunit" mystery, with many of her friends and townspeople being fellow targets and suspects.
Scream revitalized the slasher film genre in the late 1990s, similar to the impact Halloween (1978) had on late 1970s film, by using a standard concept with a tongue-in-cheek approach that combined straightforward scares with dialogue that satirized slasher film conventions.
The film opens with young Casey Becker (Drew Barrymore) recieving phone calls from an unidentified caller. At first it seems as if he has gotten a wrong number, but it soon becomes clear he is toying with her, and his voice gets more and more threatening. Casey becomes frightened when she realizes her caller can see her. She begins to panic when the caller threatens to kill her, and forces her to answer movie trivia in exchange for her life and the life of her boyfriend, Steve, who she sees tied up on her back patio. After killing Steve, the caller torments Casey until finally breaking into the house and chasing her; he is dressed in a black costume with a white ghost mask over his face. He chases her across her lawn just as her parents pull up into the driveway. They do not see her, and Casey is stabbed in the chest, unable to scream. After killing Casey, the murderer strings up her body in the back yard for the parents to discover.
Looking back at my post on conventions of a Horror Movie, the first 5-10 minutes of the opening sequence of Scream is full of the conventions, a typical horror movie in the first 5 minutes. They have created supence with the girl being on her own, a lot of shadows created because if the limited lighting created by just the odd lamp in each room and also the blue light from the TV which is blank. There is murder the death of her boyfriend and then herself, creating the use of blood and also the use of weapons. The darkness together with the eerie music and an isolated house as the setting, is a typical horror movie conventions, the chase sequence through the house and into the garden, the gore, the violence, and the screams all put together in the first opening sequence to Scream creating a really good horror movie creating suspence throughout and making you want to watch the rest of the film to find out the story behind the killer and the murderes motivation.
