Night of the Ghouls is a horror film written and directed by Ed Wood. The film features some reoccurring cast members and characters from Bride of the Monster, including Tor Johnson reprising his role of Lobo and Paul Marco again playing the character of Kelton, while the Amazing Criswell plays himself in the frame story of the film. Another returning character is Police Captain Robbins of Homicide, although the character is played by Harvey B. Dunn in Bride, and by Johnny Carpenter in Night. (Dunn however does appear in Night, albeit playing a different character).

Filmed in late 1957, Night of the Ghouls was never released theatrically nor shown on television and was thought for years to be a lost film. It was finally released direct to video by Wade Williams in 1984.
