Ghostface is the name of a fictional character and the main antagonist in the Scream trilogy. There have been five people to assume his mantle (from Scream, Scream 2 and Scream 3). A serial killer, he (or she) often dresses up as a variation of a ghost, or the Grim Reaper (The name given to his costume in the film is 'Father Death'). He also uses a device to disguise his voice. He is voiced by Roger L. Jackson (when the killer uses the voice disguiser; when the killer's mask is off, the character who is the killer talks regularly).
Ghostface is named after the rubber mask under which he hides his face, a mask inspired by the Edvard Munch painting The Scream. He is also known as the Woodsboro Killer, after the town where he commits his murders.
Ghostface often calls his victims on the phone, taunting or threatening them before stabbing them to death with an 8 inch hunting knife. Even though he is usually known for asking his victims horror film trivia while stalking them, he only does this six times in the Scream Series. (Casey in Scream, Call to Sidney in Scream, Randy's call in Scream 2, Cici's call in Scream 2,Sarah's call in Scream 3,and Cotton's call in Scream 3)
