John Carpenter’s classic ‘Halloween’ is an independent horror film produced on a shoestring budget in the unlikely year 1978. Written in 10 days and shot in just 20 days, the film follows in the extreme footsteps of Alfred Hitchcock’s ‘Psycho’, while pioneering many characteristically unique plot twists (such as the concept of the killer dying and coming back to life again within the same film). Halloween went on to become one of the most widely imitated films of the slasher genre. The basic plotline of Halloween is as follows:
On Halloween night of 1963, in Haddonfield, Illinois, 6-year-old Michael Myers, dressed in a clown costume and mask, [inexplicably] kills his older sister Judith with a kitchen knife at his home and is subsequently arrested, knife in hand. [Years later], on October 30, 1978, the now 21-year-old Michael (Nick Castle) escapes Smith’s Grove Sanitarium (where he had been committed after the murder), and steals a car that was to take him to court. Along the way, he kills a mechanic and takes his uniform overalls. He drives home to Haddonfield and steals a white [Shatner] mask from a local store. 
The maniac proceeds to terrorize Haddonfield, and much gibbitude ensues as Myers, now a giant of a man in black mechanic’s coveralls and expressionless white mask, embraces his destiny as a murderer of multitudes. Attempting to thwart Michael Myer’s extravaganza of mass murder is Dr. Sam Loomis (played by Donald Pleasence), Myer’s former psychiatrist.
Loomis, it seems, has struggled for years to keep Myers locked away, and anticipates Michael’s return home after his escape, suspecting his terrible intentions. In one scene Dr. Loomis reveals that he has worked arduously on Myers rehabilitation but has ultimately resigned himself to what Michael Myer’s really is. In a revealing discussion with the town Sheriff, Leigh Brackett (Charles Cyphers), Loomis explains his medical conclusion after years of working with Myers:
(continuing, looks at Brackett)
I suppose I do seem a bit sinister for a doctor.
Looks like to me you’re just plain scared.
I am. (he glances around the bedroom)
I met him fifteen years ago. I was told there was nothing left, no conscience, no reason, no understanding, in even the most rudimentary sense, of life or death or right or wrong. I met this six-year-old boy with a blank, cold emotionless face and the blackest of eyes, the devil’s eyes. I spent eight years trying to reach him and another seven trying to keep him locked away when I realized what was living behind that boy’s eyes was purely, simply evil.
