Ghostface (alternatively stylized as Ghost Face or GhostFace) is a fictional identity adopted by several characters in the Scream series. The figure was created by Kevin Williamson, and is primarily mute in person but voiced over the phone by Roger L. Jackson, regardless of who is behind the mask. Ghostface first appeared in Scream (1996) as a disguise used by teenagers Billy Loomis (Skeet Ulrich) and Stu Macher (Matthew Lillard), during their killing spree in the fictional town of Woodsboro. Ghostface was created by screenwriter Kevin Williamson. The mask was created and designed by Fun World costume company employee Brigitte Sleiertin as a Halloween costume, before being discovered by Marianne Maddalena and Craven for the film. The identity is used primarily as a disguise for the antagonists of each film to conceal their identities while conducting serial murders, and as such has been portrayed by several actors.
