In conceiving a new script, Morgan had intended to rework elements of the original film that were left ambiguous or implied, such as the cryptic phone calls received by the sorority house. While writing the screenplay, Morgan received input from the film's original director, Bob Clark, who also signed on to co-produce the remake. Clark gave Morgan his "blessing," stating in an interview that the remake was "still "Black Christmas"," but explored new subplots that had not been fleshed out in the 1974 film.
