Howling II: Your Sister Is a Werewolf is a 1985 American horror film directed by Philippe Mora and direct sequel to the 1981 film The Howling. The film stars horror film veteran Christopher Lee, Reb Brown, Annie McEnroe and Sybil Danning and focuses on a group of people trying to stop werewolf queen Stirba and her group's plans to conquer the world. Although Gary Brandner, author of The Howling novels, co-wrote the screenplay, the Howling II: Your Sister Is a Werewolf is largely unrelated to his 1979 novel The Howling II.
