This document provides an analysis of the 1978 horror film Halloween directed by John Carpenter. It summarizes that Halloween was notable as one of the first "babysitter horror" films focusing on teenage babysitters being stalked by an escaped mental patient. The film was commercially successful, helping establish the slasher film genre. An analysis of scenes from the film discusses how the obscured and masked killer Michael Myers creates unease in viewers and how the final girl heroine Laurie is portrayed as more masculine than her victims to explain why she survives. The popularity of slasher films is attributed to appealing to societal fears while requiring minimal deviation from profitable formulaic plotlines.
