This film features more nudity and graphic gore than most of Paul Naschy's other El Hombre Lobo films.
One of the characters in the film is named Larry Talbot. Lawrence (Larry) Talbot was the name of the role portrayed by Lon Chaney Jr. in The Wolf Man (1941).
The film was banned in the UK in 1983 after its inclusion on the DPP's (Department of Public Prosecutions) list of 72 video nasties.
Paul Naschy followed up this film with a sequel called Return of the Wolf Man (a.k.a. The Craving) in 1981.
