Howling II: Your Sister Is a Werewolf (original title:
Howling II: Stirba – Werewolf Bitch) is a 1985
horror film directed by
Philippe Mora, as a sequel to the 1981 film
The Howling. The film stars horror film veteran
Christopher Lee along with
Reb Brown and Annie McEnroe as they try to defeat
Sybil Danning's werewolf queen Stirba and stop werewolves' plans to conquer the world. Although
Gary Brandner, author of
The Howling novels, co-wrote the screenplay, the
Howling II film is largely unrelated to his
Howling II novel from 1979, though it does introduce Eastern European customs and Romani into its werewolf mythology like the book.
