Actress Carla Hoogeveen, who played Beverley, also starred in writer-producer-director Terry Bourke's previous picture Night of Fear (1973). This movie was their final feature film collaboration.
The house and the area around the homestead seen in this movie are now underwater due to the construction of a dam.
This is the only theatrically released Australian feature film starring expatriate Australian Dame Judith Anderson. She was born in Adelaide, South Australia, and mostly worked on the stage and in American films.
Australian movie posters for this movie ran with the blurbs: "In the tradition of Hitchcock comes the classic Australian suspense thriller", "MYSTERY...MURDER...MADNESS" and "You will never be the same again when you discover the secrets of Inn of the Damned".
With a budget of A$417,000, producer Rod Hay on the audio commentary refers to the picture as the most expensive Australian film ever made.
