The 1984 film had become quite dated and tedious to those who had seen it before, and there was an option for either the long or short versions of the outtakes in the ride's pre-show to be played.

The ride's winding backdrops were perfect for the cast members dressed as monsters who could scare the passing guests.

[12] Gremlin Invasion remained open until mid-September 2004, a month before the closure of Warner Bros. Movie World Germany on 31 October 2004.

[20] The unloading station still exists (albeit with theming removed) and is used as an evacuation path from Scooby-Doo Spooky Coaster.

In Van Helsing's Factory at Movie Park Germany, the movie theatres are used for the queue and pre-show, the Factory Shop (souvenir shop) and for storage; the first chain lift hill is located near Gremlin Invasion's unloading station, which still exists, an ALF animatronic is seen inside the crane at the last turn before the second lift hill, one of the telephone booths from Gremlin Invasion's prop dock is featured at the end of the ride, and the fire truck at the end of Gremlin Invasion is seen in the scrapyard.

A Gizmo animatronic was initially hidden in the engine of one of the scrapyard cards, but was removed and relocated to the ride's maintenance area shortly after its opening, due to Warner Bros. taking issue with it being seen by the guests without any license paid by Parques Reunidos.

The Gizmo animatronic from the ride's loading station can be found in one of Movie Park Germany's meeting rooms.

[11][35][36][37] After exiting the theatre and going down a corridor with a Gremlin hanging from the ceiling and cackling, guests enter the loading station/control room, where they find an animatronic Beetlejuice, who has been brought in by Warner Bros. to lead the guests to safety, and is seen facing four televisions that function as video surveillance cameras, as their screens display different rooms in the ride.

The guests are taken for a slow trip through the vault, editing rooms, the prop dock and the film laboratory, with Beetlejuice appearing periodically during the tour as the Gremlins wreak havoc.

The guests stop at some doors as they hear sirens wailing and police cars screeching their tires and crashing from outside, before exiting the building and being unloaded.

As ALF screams in terror and calls for an exterminator, other Gremlins pop out and begin destroying the set and attacking the television crew.

Guests then go past the editing rooms, where the Gremlins tie a projectionist up in film and lower and raise him from the ceiling, stand on their heads while watching television, perform hula dances, mess with ALF's face as Gizmo watches on from a film can, ride each other like cowboys, and hold ripped paper as the scene from Gremlins 2: The New Batch in which Gizmo multiplies plays on two monitors.

Gizmo helps ALF escape from jail, and as the latter sits atop a tower made of televisions (and a computer monitor), they start planning their method of getting rid of the Gremlins.

Finally, the guests' vehicle enters the shipping dock/lighting room, where the Gremlins are spraying each other with water from fire hoses and cackling.

The guests stop at some doors as two surviving Gremlins pop out of crates, and the sound of a siren wailing is heard, followed by a loud crash.

Classics and The Great Gremlin Adventure was originally designed by Village Roadshow Theme Parks for Warner Bros. Movie World in Australia.

[42] Alan Griffith Architect formed a strong working relationship with Warner Bros. International Recreation Enterprises on the ride.

[3][4] The audio-animatronics featured in the ride were built by Showtronix, designed by Greg McKee, Matt Ward, John Cox and Chris Chitty.

They were raced out in a very short time frame in large numbers, with some of them lacking articulated faces or body parts.

[9] The Batwing that one of the Gremlins flies in the prop dock was a full-size replica donated to Warner Bros. Movie World by a local propmaker.

[52] The German ride, Gremlin Invasion, was manufactured by Intamin, Australian Electric Vehicles and Barbisan & Brügger AG, and like Warner Bros.

[43][56] The ride's theming (including the black-and-white background from the prop dock) was designed and painted by Botticelli's - Atelier der angewandten Malerei and Sanderson Group.
