Daniel Kremer: [Handwritten letters] A disturbing "snail mail" letter written to Terry and Tessa functions as the film's "McGuffin"
Daniel Kremer: [Movie within the movie] Tessa is watching the independent film A Cool Sound from Hell (1959) on television as Terry arrives home one night. The film was especially licensed from its director Sidney J. Furie, on whom filmmaker Daniel Kremer wrote a full 430-page biography. The inclusion of the film is one of five direct homages to him.
