Halloween (1978)

In John Carpenter's low-budget, quintessential slasher film, set in 1963 in the town of Haddonfield, IL:

• the opening sequence of six year-old Halloween-masked killer Michael Myers (Will Sandin as boy) stabbing his 17 year-old sister Judith (Sandy Johnson) after she had sex with her boyfriend Tommy (David Kyle); the clown-costumed, insane boy stood there motionless on the front lawn, surrounded by shocked adults (his parents)

Murder of Judith

• the subjective point-of-view camera angles in the stalking of 17 year-old teenaged babysitter Laurie Strode (Jamie Lee Curtis) by 21 year-old escaped insane asylum inmate Michael Myers (Tony Moran), especially the ones in which the psycho-killer appeared and then disappeared
• the scene of the impaling of Lynda Van Der Klok's (P. J. Soles) boyfriend Bob (John Michael Graham) against a wall with a large butcher knife and then - while wearing a white sheet draped over himself and with Bob's glasses perched on his face - strangling Lynda with a phone cord while she was on the phone, making her death screams sound like she was having an orgasm
• the innumerable times that maniacal white-masked Shape/Michael Myers (Nick Castle) came alive again
• the sequences of Laurie's fighting back throughout the Doyle house: downstairs with a knitting needle (plunged into his neck), and in an upstairs closet with a metal coat hanger (stuck into his eye), and with his own dropped knife (thrust into his torso) - but the white-masked Shape seemed indestructible, especially in the startling, scary moment when the seemingly-dead Michael Myers sat up in the background behind a sobbing Laurie after she had left the closet. After he approached and assaulted her again, as he grabbed Laurie's neck and strangled her, she brushed the mask from Michael's face. Michael let go of her neck to put his mask back on to restore his masked facade
• shrink Dr. Sam Loomis' (Donald Pleasence) horrifying discovery that the killer ("boogeyman"), who was stabbed three times and shot six times, had vanished from the ground below after a fall from the two-story balcony - and hadn't succumbed

• the final dialogue: bloodied and in near-shock, Laurie quizzically stated: "[it]...was the boogey-man," while Dr. Loomis confirmed: "As a matter of fact, it was..."
