2. The Goonies – Giant Octopus
This may not be one that younger readers will know but there was a glaring mistake for people who saw Goonies in the movie theater. At the end of the film, Data tells the police about battling a giant octopus. The problem with this scene is that the giant octopus was cut from the film. So viewers who saw the movie in the theater had no idea what Data was talking about at the end of the film.
