It put the slasher sub-genre on the map, launched Jamie Lee Curtis's career and introduced the world to a Shatner-faced killer who is now a horror icon.
John Carpenter's seminal murder fest Halloween stalked its way into cinemas way back in 1978, FORTY YEARS AGO and had a generation of film fans jumping at shadows and sleeping with one eye open for many nights to come.
Michael Myers was an instant hit with horror hounds and his killing spree across the sleepy town of Haddonfield left them screaming for more.
To say they got their wish is putting it lightly as Halloween spawned numerous sequels and the series has since been rebooted more times than that third-hand Dell computer you picked up on the cheap at the local car boot sale. Although the original is regarded as a low-budget horror classic, its follow-ups are mostly known for being, at best, guilty pleasures, and at worst a complete waste of time and celluloid.
Like most long-running slasher franchises, the Halloween series has produced almost as many gaffes and facepalms as satisfactory jump-scares and epic kills over the years, and these egregiously dumb moments are almost on the same level as the decision to flee from the killer through the doggie door in the first Scream movie.
