Trivia: Notably, the previews for this film (and several other sequels in the series) contained footage not seen in the finished movie. The previews were often made primarily of footage from alternate and deleted scenes. The producers and directors hinted that this was done to help keep the story secret, despite being a bit shady on their part.
