Simon (Sir Patrick Stewart) re-enacts a scene with Virginia from Hamlet where the title character is speaking with his father's ghost, who reveals he was slain by his own brother Claudius. Sir Patrick Stewart played Claudius in Hamlet, Prince of Denmark (1980), and Hamlet (2009).
When the film was initially released in Japan, they retitled it "Ghost Scream" to capitalize on Neve Campbell's popularity of the movie Scream (1996), which came out some months after the movie was released. This change was reverted for the Japanese DVD release.
Sir Patrick Stewart and Cherie Lunghi played father and daughter in the 1981 film Excalibur. Stewart portrayed King Leondegrance and Lunghi portrayed his daughter, Guinevere.
