* AllStarCast: Creator/JamesMcAvoy, Creator/EmilyBlunt, Creator/JasonStatham, Creator/PatrickStewart, Creator/MaggieSmith, Creator/MichaelCaine, Wrestling/HulkHogan, Music/DollyParton, Creator/JimCummings1952, Music/OzzyOsbourne…
* BreakawayPopHit: This film's cover of "Crocodile Rock" was a major success on Radio Disney's top 30 back when the film premiered, actually surpassing the popularity of several Music/JustinBieber songs on there.
* ChannelHop: The sequel was released by Creator/{{Paramount}} and MGM, as opposed to Touchstone.
* CreatorsOddball: More accurately, a distributor's oddball. Disney's Touchstone Pictures label is known for distributing films [[DarkerAndEdgier aimed at an older audience]], but ''Gnomeo and Juliet'' is the first movie distributed under them [[LighterAndSofter that is rated G]] since the 1998 US release of ''Anime/KikisDeliveryService''.
* TheDanza: Dolly Gnome, being a [[InkSuitActor direct caricature]] of [[Music/DollyParton her actress]].
* DevelopmentHell: Following the success of his work on ''WesternAnimation/TheLionKing1994'', Disney executives greenlit ''Gnomeo and Juliet'' in the late '90s to essentially serve as a vehicle for Music/EltonJohn's music catalogue, though the movie suffered a notoriously troubled in-house development with the directors and animators not having much of an idea of how to make the film work. When Creator/{{Pixar}}'s John Lasseter was placed in charge of Disney's animation studio in 2006, he was given a briefing on the films that the studio had in development. When they got to ''Gnomeo'', Lasseter bluntly asked "Wait, why exactly are we making this?", to which no one in the room could give him an answer, so the film was cancelled. In 2007, the film rights were transferred to Starz Animation, who made the movie that we have today.
* NoExportForYou: In Japan, this was never released. Despite this, the sequel WesternAnimation/SherlockGnomes was released DirectToVideo in Japan, [[Main/MarthDebutedInSmashBros leading the appearance of the characters from Gnomeo and Juliet to be the first time they showed up in Japan.]] What’s even more confusing is that the reference to the former movie in the opening scene was kept in the Japanese dub despite the film in question not being dubbed.
* PlayingAgainstType: Music/OzzyOsbourne as possibly the cutest little faun you'll ever see.
* SequelGap: ''Sherlock Gnomes'', announced just a year after the first film's release, wasn’t released until seven years after the first ''Gnomeo'', an extraordinarily long gap for a non-nostalgia/legacy-based sequel to a children's film.
* StuntCasting:
** Wrestling/HulkHogan plays the guy in the Terrafirminator commercial.
** Music/DollyParton as Dolly Gnome, the female gnome who announces the lawnmower races.
