9. Silent Night, Deadly Night (1984)
'Naughty' Billy Chapman is a troubled teen who grew up in an orphanage after unfortunately witnessing his parents' malicious murder by Santa Claus (a disguised murderer). Unsurprisingly, fuelled by his hatred of Santa Claus, Billy becomes a serial killer himself (also dressed in a Santa-suit) in controversial cult horror Silent Night, Deadly Night. Although Billy is simply a misunderstood guy under the fake beard, this film has been an acquired taste during a time that is meant to be associated with anything BUT horror - especially a serial killing Santa! Following four slashing sequels... a remake directed by Steven C. Miller was recently released as Silent Night (2012). Although it isn't the cheerful image of Santa we have all grown up believing, Killer Claus is a classic cult character for some.
