Black Christmas is a Canadian-American horror franchise that consists of two slasher films, a novel and merchandise. The films have collectively grossed over $25 million at the box-office worldwide.
The franchise began with the 1974 film Black Christmas which was directed by Bob Clark and starred Olivia Hussey, John Saxon and Margot Kidder. Based on the urban legend "The Babysitter and the Man Upstairs" and a series of real murders in West section of Montreal, Quebec, the plot focuses on a mysterious deranged stranger sneaking into a sorority house where a group of sorority sisters reside in, and begin to receive threatening phone calls by the stranger before getting murdered one by one inside the house. Receiving a positive reception and generally considered to be one of the earliest slasher films that would later inspire Halloween, it has since gained a cult following and received a novelization in 1976 written by Lee Hayes.
In 2006, the remake of the same name was released. It was directed by Glen Morgan, produced by Bob Clark and starred notable actors including Mary Elizabeth Winstead, Katie Cassidy and Oliver Hudson. Unlike the original film, the remake instead focuses on the killer named "Billy" (that was more ambiguous in the original film), and included much more gore and violence than that of the original. Upon its release, its reception was much more unfavorable.
