It was years later released on DVD as The Werewolf and the Yeti [2] Naschy followed up this film with a 1980 sequel called El Retorno del Hombre Lobo/Return of the Wolf Man.

Waldemar Daninsky goes to Tibet to guide an expedition led by Professor Lacombe to look for proof that the yeti exists.

In the film's grand climax, Waldemar (in werewolf form) gets to fight not only Sekkar Khan, the bandits' leader but also a genuine Yeti in bloody hand-to-fang combat.

The professor's daughter Sylvia, who is in love with Waldemar, manages to cure him of his lycanthropy by rubbing a small Tibetan flower mixed with her blood on him.

The film was released on VHS Home Video in the 1980s under three different titles... Hall of the Mountain King (severely edited), Night of the Howling Beast and The Werewolf and the Yeti.
