* ActorSharedBackground: The late Benjamin Whitrow (Fowler) served in the 1st King's Dragoon Guards from 1956 to 1958 before he became an actor.
* AwesomeDearBoy: When Peter Lord and Creator/NickPark first pitched "''Film/TheGreatEscape'' with chickens" to Steven Spielberg and Jeff Katzenberg, Spielberg immediately agreed to the project because ''Great Escape'' was his favorite movie ''and'' he owned a small chicken farm!
* CelebrityVoiceActor: The European French dub has Creator/GerardDepardieu as Rocky, Creator/ValerieLemercier as Ginger and Creator/JosianeBalasko as Bunty.
* CrossRegionalVoiceActing: Creator/MelGibson was the only one in the cast to record his lines as Rocky in a US studio while the rest of the cast recorded in England.
* DeletedScene: One scene that was cut was how Rocky stole a tricycle from a child. In the theatrical release, this causes some "huh?" as to ''how'' Rocky was riding a tricycle in the first place. This was a ShoutOut to ''Film/TheGreatEscape,'' where Virgil Hilts steals a motorcycle from a Nazi soldier.
* DuelingDubs: There are two French dubs of this film, the first one was made for its Canadian release and another one for France with {{Celebrity Voice Actor}}s and different dubbers. Both dubs were recorded at Dubbing Brothers with Jean-Pierre Carasso and Jean-Marc Pannetier acting as dialogue adaptors for both versions.
* DVDCommentary: By directors Peter Lord and Nick Park.
* ExecutiveMeddling:
** Creator/DreamWorksAnimation and composer Music/HansZimmer (who heads [=DreamWorks=] Music) forced director Creator/NickPark to drop an already-recorded musical score by ''WesternAnimation/WallaceAndGromit'' composer Julian Nott because Zimmer decided to have John Powell and Harry Gregson-Williams write the music together. It was meddling like this which resulted in Aardman and [=DreamWorks=] eventually parting ways after three films.
** Jeff Katzenberg also made the filmmakers add a shot of Mr. Tweedy playing with a torch after Mrs. Tweedy tells him to get one from the house because he assumed most Americans wouldn't know that what they called "flashlights" are called "torches" in England (and would be wondering why Mr. Tweedy wasn't carrying [[JustForFun/IThoughtItMeant a large, flaming stick]]).
* IWantYouToMeetAnOldFriendOfMine: Creator/MirandaRichardson, Creator/JuliaSawalha, and Creator/JaneHorrocks all worked on ''Series/AbsolutelyFabulous.''
* KidsMealToy: It got Burger King playsets involving cannons, airplanes, and a high-wire act. [[BrokenAesop Infamously, it was marketed with chicken nugget-esque products, despite the theme of the movie and the Burger King marketing itself being against eating chicken.]]
* LateExportForYou: The film wasn't released in Japan until 2001, nearly one year after its initial North American release.
* TheMerch: Creator/PlaymatesToys had a ''Chicken Run'' toyline when the movie came out; the [[https://imgur.com/a/wu2RWrA Pie Machine]] was a re-deco of an [[http://www.tmnttoys.com/89vehicles/pizzathrower/index.html earlier]] ''Franchise/TeenageMutantNinjaTurtles'' toy.
* NoExportForYou: The two video games were not released in Japan.
* PlayingAgainstType: While he does have moments of genuine heroism, Rocky is an immature, cowardly show-off who isn't nearly as competent as he tries to present himself, a far cry from Creator/MelGibson's usual serious, action hero roles.
* UncreditedRole: Creator/CosgroveHall made an oversized model of Mr. Tweedy for scenes where he kicks or grabs Ginger.
* WhatCouldHaveBeen: [[WhatCouldHaveBeen/ChickenRun Now has its own page.]]
* WriteWhatYouKnow: Creator/NickPark had pet chickens in his youth, several of whom frequently tried to escape their pen. Two of them were even named Ginger and Rocky.
