!![[Film/TheGoonies The film]]
* AbsenteeActor: In the ''MAD'' satire "Goofies," Stef never appears.
** Kerri Green (Andy) is not in Cyndi Lauper's "Good Enough" music video, as she busy starting work on the film ''Lucas''.
* AdaptationExpansion: The novelization extends the story further, showing Sloth adapting to his new life as a member of Chunk's family.
* TheDanza: The Goonies' real parents -- except for Mikey's and Brand's, of course -- were filmed as their characters' parents in the ending's reunion scene.
* DawsonCasting: Almost completely averted (e.g. 13-year-old Sean Astin as the 13-year-old Mikey), with the exception of teen JerkJock Troy played by 26-year-old Steve Antin.
* DeletedScene:
** Data at the end saying that the octopus was very scary, which was cut from the final film (although showed up in some television versions).
** In the end, Stef thanks Mouth for saving her in a scene that was also cut.
** Another DeletedScene on the DVD shows the Goonies stopping at a convenience store, where Mikey matches the treasure map to a modern map. Troy takes the treasure map, rolls it, and lights it like a big cigarette/cigar.
** The octopus is referenced in the ''Magazine/{{MAD}}'' version.
-->'''Girl:''' Wow, he must be some big stud! Where is he?
-->'''Boy:''' You misunderstood! I said I saw two giant ''tentacles'', not... oh, never mind!
* EnforcedMethodActing:
** The kids weren't allowed to see the pirate ship until the filming of the scene in which they see it for the first time. Unfortunately, the first take wasn't used, as several of the cast blurted out an unscripted "Holy ''shit!''"
** Jeff Cohen, who played Chunk, was told that the scene where Sloth picks his chair-tied self up would cut before the actual lift occurred; it obviously didn't, and John Matuszak straight-out picked him up easily, leading to the kid's wails and cry of, "You smell like phys. ed.!"
* HeyItsThatGuy: [[Film/TheMatrix Cypher]] and [[Film/LicenceToKill Franz Sanchez]] are Francis and Jake Fratelli, respectively. Mama Fratelli was played by [[Film/ThrowMommaFromTheTrain Momma]].
** [[Film/TheLordOfTheRings Samwise Gamgee]] is Mikey.
** [[NoCountryForOldMen Llewelyn Moss]] (and later, [[MarvelCinematicUniverse Thanos]]) is Brand, believe it or not.
** [[Film/TempleOfDoom Short Round]] is Data.
** [[TheLostBoys Edgar Frog]] is Mouth.
** [[Creator/RichardDonner Yeah that'll be the day]] when The Goobers find the treasure!
** Sloth was played by John Matuszak, a football player for the Oakland Raiders and a SuperBowl champion. He had previously played the tribe-leader Tonda in 1981's ''Film/{{Caveman}}'' opposite RingoStarr.
* ThrowItIn: Most of Chunk's confessions (except the fake puke story) were based on actor Jeff Cohen's life. According to Jeff, it was a different kid who was kicked out of fat camp for pigging out.
