Rob Craig suggests that the film could be in part based on an earlier work,
Sucker Money (1933), produced by
Willis Kent. The two films have significant similarities in concept. In the earlier film, Swami Yomurda (
Mischa Auer) and his minions stage an elaborate scheme to extort money from gullible victims. Yomurda and his group use technological means to convince their victims that they are receiving
audiovisual from the
otherworld.
Tor Johnson also plays a character called "Lobo" in both films, and both of the Lobo characters are monstrous manservants working for the main villains. Both films were shot around the same time, though it is unclear if one was intentionally modeled after the other. The notion of a genuine ghost and a fake one that are active on the same area is not unique to this film.
The Ghost Breakers (1940) has a real ghost appear in the end,
Spook Chasers (1957) has a real ghost among several fakes, and
Ghost of Dragstrip Hollow (1959) has a real ghost residing in a "fake" haunted house. Craig considers the film to have elements common in
absurdist fiction, and also to have much of the pessimism and nihilism of a typical
Samuel Beckett play. The film's main setting is the rebuilt house on Willows Lake that burned down in
Bride of the Monster. There are frequent references to the mad scientist (
Bela Lugosi) and Lobo (Tor Johnson), the latter of whom returns, his face now half-destroyed from the fire. Wood, his face hidden by a dark veil, doubled for the Black Ghost in several shots. According to actor
Paul Marco, Wood could not get Jeannie Stevens to film these scenes. So he wore the costume and acted as her stand-in. Also, a publicity photo of Wood is seen on a wanted poster on the wall of the police station.
Night of the Ghouls is the third part of what Wood aficionados refer to as "The Kelton Trilogy", a trio of films featuring
Paul Marco as "Officer Kelton", a whining, reluctant policeman. The other two films were
Bride of the Monster and
Plan 9 from Outer Space. ==Release==
