* BannedInChina: And just about everywhere else, for that matter.
* CanonDiscontinuity: Disney's official take on the film is to pretend it doesn't exist.
* CultClassic: The film, despite its rarity and extremely ill repute, has still gained a tiny, largely anonymous yet persistent fanbase. For more in-depth information, see MisaimedFandom.
* ExecutiveMeddling: [[DevelopmentHell This was originally going to be finished by 1986]], and be a much darker PG-rated piece with no songs and Anne was actually going to die in the end. And it was written by Creator/HarlanEllison. However, after ''Disney/TheBlackCauldron'' flopped in 1985, Disney execs and Molly Ringwald's ego stepped in and retooled it completely again. Also a case of WhatCouldHaveBeen.
* HeyItsThatVoice:
** Miep is voiced by Creator/JasonAlexander, [[WesternAnimation/ThePagemaster Horror]] as Ludvig, [[MollyRingwald Samantha Baker]] as Anne, [[Creator/TomCruise Maverick]] as Peter, Music/{{Madonna}} as Sgt. Olga, Creator/ChristopherWalken as Josef Mengele, Creator/TimCurry as Churchill, Creator/RobinWilliams as Franklin D. Roosevelt (uncredited, but unmistakable), Creator/FrankOz as the ghost of Kaiser Bill, [[Creator/BillMurray Carl Spackler]] as Bob the Zombie, and {{Music/Prince}} as Kaiser Billy's singing dog.
** Listen closely to Jackie Robinson's voice. That's Creator/WillSmith[[note]]credited as "the Fresh Prince"[[/note]] in his acting debut, one full year before ''Series/TheFreshPrinceOfBelAir''. (Scratching, as always, provided by DJ Jazzy Jeff.)
*** This is also true for the foreign versions of the film: in the Italian dubbing, for example, Sgt. Olga is voiced by Amanda Lear. In the 2010 Japanese DVD/BD edition, Anne is voiced by Creator/MaayaSakamoto, and Peter by none other than TakuyaKimura.
* KeepCirculatingTheTapes:
** Almost all of the master tapes, cells, and original drawings were reportedly destroyed shortly after the film was released. You can find a full copy of it on pirated tapes of ''Bambi 2002''.
** The Latin American cut has only one known film reel to have survived, it resides in a museum in Santiago, in a room unavaiable to the public. It's screened only once a decade and you have to pay an exorbitant fee to see it.
** The only DVD release thus far is a 20th anniversary edition for the Japanese dub in 2010 (which, ironically, also contains a new dub). It exists because the anime versions of ''Theatre/TheDiaryOfAnneFrank'' are very popular in Japan, which has very few Jews and hence very little cultural sensitivity to what happened during the Holocaust.
* MisaimedFandom: A noticeably large portion of this film's cult followers is made up of Neo-Nazis and other equally-minded individuals ([[NoEndorHolocaust for]] [[EvilIsCool obvious]] [[EvilIsSexy reasons]]), even though the director himself said that he didn't intend to outright lionise the Nazis, but to '[[{{Bowdlerize}} disarm]]' some of their more disturbing deeds so it wouldn't scare children in the audience.
* OldShame: If you talk to any of the actors mentioned on this page, as well as anyone who worked at Disney in the late 1980's, they will totally act like this movie never actually existed and that they don't know what you're talking about. Go on, try it!
* ThrowItIn: Madonna came up with Sgt. Olga's surname.
** Originally, Olga's dog was not named. It wasn't until some of the actors nicknamed it "Mr. Goebbels" was it put in the script.
* WhatCouldHaveBeen: There were some reports of adding an attraction based on this movie to Disney World; namely the German Pavillion of EPCOT was to have added an Auschwitz-related attraction. The reports did not have any details on what exactly the attraction would consist of other than it would be "designed to be entertaining, but educational at the same time". However, before more details could be discerned, the severe backlash from the movie resulted in the project never being mentioned again.
** [[TheWho Pete Townshend]] was considered for composing the film's score, but he backed out because he was too busy recording ''The Iron Man''. It makes you wonder how it would've turned out.
** Due to the success of the movie's DVD release in Japan (see KeepCirculatingTheTapes above), a world based on the movie was allegedly planned for ''KingdomHearts3D'', complete with boss battle against Mengele in his Archangel form. However, halfway through development, Tetsuya Nomura realized how bizarre and insensitive the concept was, and the world was removed and hastily replaced with one based on ''MickeyDonaldGoofyTheThreeMusketeers''.
*** Relics of the battle's concept can still be seen in the fight against the Belief boss in {{Bayonetta 2}}, however.
