Trivia: Sybil Danning agreed to do the film, but only if she didn't have to do excessive nudity, as she was getting sick of doing nude scenes. The producers agreed to limit the amount of nudity she'd have to film. But in a tricky move, they then recycled a shot of her ripping off her top and replayed it over and over during the end credits - 17 times in total - in order to capitalize on her sex appeal. Danning was reportedly furious when she saw the edited credits.
Trivia: The only "Howling" movie co-written by the original novel author Gary Brandner. Brandner was a bit miffed by all the changes made to the original film, and wanted to write the sequel as he saw fit. Ironically, while the original film was warmly received by critics and audiences, this sequel was universally panned and is often considered a "so bad, it's good" camp classic.
Trivia: Christopher Lee agreed to appear in the film because he had never made a werewolf movie and wanted to make one. However, he absolutely hated the finished film. He later personally apologized to original "Howling" director Joe Dante (who had no involvement in this sequel) for making the film.
