This chapter discusses the first character seen on screen in Wes Craven's Scream named Casey, portrayed by Drew Barrymore, in a sequence generally regarded as an arresting self-contained set piece. It explains how Scream serves as a short film in its own right, priming the audience for the film's principal gimmick. It also describes the way Scream acknowledges the standard role of a prologue in a slasher film, which follow the terrorisation and murder of a short-lived character as a means of establishing the antagonist prior to the introduction of the central characters. The chapter mentions the ominous caller in Scream that is voiced by Roger Jackson who represented the vocals of the killer through a universal, gender-defying voice-changing device employed by the antagonist. It talks about Scream's opening scene and the slasher format that has its origins in an enduring urban legend referred to as 'The Babysitter and the Man Upstairs'.
