->''Whatever happened to Baby Jane?\\
To her smile, her golden hair?\\
Why must everything be so unfair?\\
Is there no one left to care\\
What really happened to Baby Jane?''

A classic 1962 thriller directed by Robert Aldrich, starring Creator/BetteDavis and Creator/JoanCrawford. It was adapted from a novel by Henry Farrell.

Aging sisters Blanche (Crawford) and "Baby" Jane Hudson (Davis) live together in a decaying mansion in Hollywood. Jane had been a {{vaudeville}} child star in the 1910s, but her fame disappeared a long time ago. Blanche, meanwhile, was a successful film actress in the '30s, but was crippled in a mysterious car accident involving Jane.

Jane is mentally disturbed, an alcoholic, and greatly resents Blanche. When she learns that Blanche plans to sell the mansion and put her in a sanitarium, things really start to go downhill. Jane's mental state gradually worsens, and she becomes emotionally and physically abusive to her sister, eventually holding her hostage.

There is also a 1991 TV movie version starring real-life sisters Lynn and Vanessa Redgrave as Jane and Blanche. It doesn't seem to have been poorly received by critics, but it hasn't made much of an impression either.

Followed two years later by a SpiritualSuccessor, ''Film/HushHushSweetCharlotte'', also directed by Aldrich and starring Davis, but with Creator/OliviaDeHavilland in the Crawford part.

!!Contains examples of:
* TheAlcoholic: Jane.
* AssholeVictim: [[spoiler:Blanche, as it turns out.]]
* AxCrazy: Jane devolves into this.
* BitchAlert: The moment Jane steps off the stage in her first scene you know she's going to be trouble.
* BigFancyHouse: Jane and Blanche's mansion.
* BitchInSheepsClothing: [[spoiler:Blanche.]]
* BlackAndWhiteMorality: Subverted.
* BlackAndGrayMorality: What it actually is.
* CainAndAbel: Jane and Blanche Hudson, respectively.
* {{Camp}}: The film is known for having a fair amount of this, which helps account for its CultClassic status.
* CoolCar: Jane's 1931 Duesenberg Model J roadster (in the 1935 scenes) and 1947 Lincoln Continental convertible (in the "present day" part of the film).
* CreepyChild: Little Blanche, who seems to spend all of Jane's shows fixing her with a DeathGlare.
* CreepyDoll: The Baby Jane Hudson doll- creepy and menacing before anything even happens.
* CurseCutShort: Jane calling Blanche a bitch is drowned out by the sound of the buzzer.
* CuteButCacophonic: Baby Jane's singing voice comes off as somewhat shrill, even for a little girl.
* DeathbedConfession: On the beach, [[spoiler:when Blanche thinks that she's dying, she tells Jane the truth about the car accident.]]
* DarkReprise: When Baby Jane first sings the song [[TastesLikeDiabetes "I've Written a Letter to Daddy"]] in the beginning of the story, it just comes off as a sappy kid's song. However, it becomes incredibly creepy when she sings it later as an old woman.
** This [[https://www.youtube.com/watch?v=0NRvXdqe-tQ LP version also recorded by Davis]] just makes it worse because she's so in character. At least, until the [[MoodWhiplash change of mood]] by the third repeat of the verse.
* DaylightHorror: [[spoiler:Blanche's presumed death, and Jane's final descent into madness,]] take place at a crowded beach on a sunny day.
* DefrostingIceQueen: A really dark example. Jane starts off the film as a grumpy and bitter old woman but as she gets herself further into trouble she unravels and behaves more like a frightened child.
* EvenEvilHasStandards: Edwin may be a slimy greaseball that is just going after Jane for her money, but when he sees Blanche all tied up, he immediately runs out the door and contacts the police.
* EvilCripple: [[spoiler:Blanche.]]
* EvilAllAlong: [[spoiler:Blanche was endlessly bitter about the preferential treatment her sister got as a child. The situation only declined further when they were adults, as their careers were tied together. Every film Blanche made, one had to be made with Jane, and Jane couldn't act; meaning every flop Jane made damaged Blanche's career. Finally Blanche had enough, and tried to kill her sister, but ended up crippling herself. Blanche made it look like Jane was responsible; even Jane believed this, since she was drunk, and couldn't remember the night. Thus, she was forced to live with guilt for the rest of her life. Still bitter, Blanche forced her sister to wait on her hand and foot for thirty years before Jane loses her mind, and TheDogBitesBack.]]
* TheFilmOfTheBook
* FormerChildStar: Jane.
* GiftedlyBad: Jane. She is a terrible actress, can't sing and could only dance as a child. Jane herself thinks her talent defines her, and believes it is the one thing she can never lose.
* GildedCage: Blanche's room is quite nice, but unfortunately her sister wouldn't let her leave.
* TheGloriousWarOfSisterlyRivalry: One of the most extreme examples.
* {{Glurge}}: Invoked and parodied with "I've Written a Letter to Daddy", an awful, maudlin vaudeville number about a little girl who sends a love note stamped with kisses to her father in Heaven. It's first heard performed by Debbie Burton in the most quavering, histrionic, off-key way imaginable, just to make it all sillier; it gets even creepier when Jane, now over 55 and with her actual father long dead, performs it again.
* GoodColorsEvilColors: The fact that Jane is blonde and wears white, while Blanche has black hair and wears dark clothes, should be the first clue that all is not as it seems. It's especially noticeable because Blanche's name ''means'' "white."
* GoldDigger: Edwin is repulsed by Jane, but he still wines and dines her hoping to milk the situation for all it's worth.
* InsaneTrollLogic: While explaining how they can run away from the police and never be found, Jane delightedly remarks that they'll go to the beach and "live at the seashore all the time", where she'll invite everyone to come and visit them.
* IWasQuiteALooker: Jane was an angelic little girl and a reasonably attractive young woman but has now grown old and is a complete mess. Averted with Blanche who has aged well enough.
* KickTheDog: Jane kills Blanche's pet bird, and serves it to her on a dinner plate.
* LadyDrunk: Jane.
* LargeHam: Bette Davis' portrayal of Jane. Joan Crawford has a few moments too, resulting in HamToHamCombat.
** ColdHam: In stark contrast to [[{{Series/Batman}} some of his other roles]], Victor Buono plays almost all of his scenes as Edwin with quiet, immeasurable loathing for the people around him. It's not until he gets drunk and loosens up that he becomes a true LargeHam.
-->"Here I come, the SUPER CHIEF!" ''(Giggling)''
* MadnessMakeover: Jane went from being a very pretty but troubled young woman, to a crazy old biddy who never washes her face, styles her hair in ringlets and looks more dishevelled as her grip on sanity loosens. [[spoiler: When Jane no longer feels guilt over crippling her sister, the reverse happens - her wrinkles disappear and she looks like a happy girl.]]
* MommasBoy: Edwin.
* MyBelovedSmother: Edwin's mother is very clingy and possessive, and gets jealous when he starts spending his time with Jane.
* NiceCharacterMeanActor: Jane was a cutesy ShirleyTemple-esque child star and a horrible spoilt brat offstage.
* NosyNeighbor: Mrs. Bates is a mild example.
* NotAllowedToGrowUp: Jane, trying to look like a child.
* OneHitWonder: In-universe example: Jane with "I've Written a Letter to Daddy." [[invoked]]
* QuestioningTitle
* RageAgainstTheReflection: Jane when she gets a good look at herself in the dance mirror.
* ReallyGetsAround: Jane in the 30s, part of the reason she was TheLoad to Blanche.
* RegalRinglets: Jane's hair.
* TheResenter: Both sisters.
* SanitySlippage: Jane is mentally disturbed from the start, and goes downhill over the course the film. [[spoiler:At the end, she loses all contact with reality]].
* SelfDeprecation: When the filmmakers were looking for bad films of Bette Davis to use for Jane's bad films, she said any of her early 1930s ones would do.
* [[HeKnowsTooMuch She Knows Too Much]]: [[spoiler:Jane murders [[BlackDudeDiesFirst Elvira]], after she finds out that Jane is keeping Blanche as a captive]].
* ShrineToSelf: Jane has one of these in her room.
* SiblingRivalry
* SlipknotPonytail: Blanche's hair comes unravelled out of its updo as Jane's treatment of her worsens.
* SmallNameBigEgo: Jane has no idea that "Baby Jane Hudson" is totally forgotten, and thinks lots of people would love to see her make a comeback.
* SpoiledBrat: Young Jane was like this.
* StepfordSmiler: Blanche has always been a big one, but is forced to fake it even more to placate Jane as she gets crazier and more violent.
* StylisticSuck: Early in the film, studio executives watch scenes from Jane's films, and note that she's an awful actress. However, those were real scenes from the early movies of Bette Davis.
* TakeOurWordForIt: We never find out what Jane wrote about Blanche on the envelope containing her fan letters, with Elvira only saying, "I can't remember the last time I saw words like that written down". (In 1962, it probably would've been impossible to say such words in a movie).
* ThenLetMeBeEvil: [[spoiler: Since Jane thought ''she'' had crippled Blanche, she apparently snapped and became cruel because she thought that she was a bad person and played the part of an evil sister. When she finds out she was totally innocent, she reverts to a sweet, innocent girl - note the use of soft lighting from then on.]]
* TimeshiftedActor: Jane and Blanche as children are played by June Allred and Gina Gillespie.
* TwistEnding: [[spoiler: At the end the secret of the accident is revealed by Blanche. It was thought by everybody (even Jane, who was drunk and couldn't remember) that she tried to kill Blanche, but it was actually the other way around. Blanche tried to run over Jane, who was able to get out of the way in time, and instead Blanche snapped her own spine as the car crashed.]]
-->[[spoiler:Jane]]: You mean all this time, we could have been ''friends''?
* TheUnfavorite: Blanche in the 1910s. Her father seems to openly dislike her and though her mother is kinder to her, she is largely overlooked.
** It's quite possible the roles are reversed when the sisters go to live with their aunt, who openly favors Blanche the same way their father favored Jane.
* UncannyValleyMakeup: Jane, so, so much. Bette Davis suggested the idea she never washes her face, she just cakes new makeup on every day.
* TheUnreveal: [[spoiler:Does Blanche die there on the beach, or not? We'll never know.]]
* VillainousBreakdown: Jane goes completely insane at the end, and when she's discovered by the police, and as a crowd gathers around her, she starts her old song-and-dance routine.
* VoiceChangeling: Jane can perfectly imitate Blanche's voice.
* WhatHaveIBecome: Jane [[TomatoInTheMirror freaks out]] when she happens to glance in the mirror when she's reliving her child star career and sees her [[BeautyToBeast ravaged, sagging, horribly made up face]] staring back at her.
* WhiteDwarfStarlet: Baby Jane, of course. Also a FormerChildStar.
** Just to complete the trifecta, from what little we get to see of when she was a star, she was ThePrimaDonna. And she seems to have ''stayed'' that way...
