Though it is never credited, the film is based on Francis Marion Crawford's classic horror story of the same title, first published around 1906. Interestingly, Crawford's inspiration for the tale, in turn, came from the folklore surrounding the so-called "screaming skull" that was kept on display at Bettiscomb Manor in Dorset, England. The actual skull that inspired both the story and the movie is said to be that of a black slave whose request for burial in his native country was denied following his death and was subsequently followed by strange occurrences and unexplainable shrieking noises that emanated from the wooden box in which the skull was kept.
