Gremlin Invasion was set within a fictional movie theatre. The pre-show was a showing of classic movies, which gets disturbed by Gremlins on the loose. During the actual ride Gizmo and Beetlejuice guide guests through a variety of movie sets, in which Gremlins were playing tricks.
The design of 'Warner Bros. Classics and The Great Gremlin Invasion' was used for 'Gremlin Invasion' in Warner Bros. Movie World Germany (now Movie Park Germany). However, the German version was not a like for like copy. Most notable change is the appearance of ALF instead of Beetlejuice.
Was replaced by Scooby-Doo Spooky Coaster.
