->'''Ted Kramer''': Margaret, I just need to know something. Did you put Joanna up to this?
->'''Margaret Phelps''': No, I did not put Joanna up to this.
->'''Ted Kramer''': Give her a little pep talk, maybe?
->'''Margaret Phelps''': Joanna is a very unhappy woman and it took a lot of courage to walk out this door.
->'''Ted Kramer''': [[ArmorPiercingQuestion How much courage does it take to walk out on your kid?]]

Adapted from the novel by Avery Corman, ''Kramer vs. Kramer'' follows the story of Ted Kramer (Creator/DustinHoffman). Ted's a {{workaholic}} who is not really involved in the domestic life of his wife Joanna (Creator/MerylStreep) and 6-year-old son Billy. He is forced to become involved immediately one day, when Joanna leaves him, forcing him to raise Billy alone. A year and a half pass before she finally returns to claim Billy; an emotional custody battle ensues.

This was 1979's UsefulNotes/AcademyAward winner for Best Picture, and the film that earned Hoffman and Streep their first Oscars for Best Actor and Best Supporting Actress, respectively. Robert Benton's wins for Best Director and Best Adapted Screenplay brought the total to five.

This has nothing to do with [[Series/{{Seinfeld}} Cosmo Kramer]].

!!This film features examples of:
* AdaptationDyeJob: Joanna is brunette in the book.
* AdaptationalHeroism: In the novel, Joanna is much more self-centered and narcissistic, whereas in the movie, she comes off as genuinely overwhelmed and unhappy and in need of help. This was because Meryl Streep thought the character as originally written was too unsympathetic, and the filmmakers agreed with her. (So did everybody else, if $106m return on a budget of $8m and five Oscars are anything to go by.[[note]]Best Picture, Best Director, Best Adapted Screenplay, Best Actor for Hoffman and Best Supporting Actress for Streep.[[/note]])
* AdultFear: When Ted sees Billy fall from the jungle gym and hurt himself badly. After that scene, you'll understand how Ted is sprinting like a Olympic track star with Billy in his arms to the hospital. The fact that the kid needs stitches and Ted can only hold him as they are painfully sewn is equally painful for the audience too.
* CallBack: The first meal Ted tries to make his son is french toast, which ends up going terribly due to his inexperience. On their final day together, the two make french toast again, but this time it is much easier.
* CharacterDevelopment: Ted, practically an absentee dad at the beginning (see EstablishingCharacterMoment below) becomes a caring and devoted father.
* ADayInHerApron: More like at least a year and a half, but the trope still fits.
* DiegeticSwitch: Antonio Vivaldi's "Mandolin Concerto" plays over the opening credits and scenes, as Ted is finishing up a meeting with his boss and Joanna is packing to leave. Then it's being played onscreen by two street musicians Ted passes, before it switches back to background music.
* DoorClosesEnding: The elevator doors close on Ted as Joanna goes upstairs to tell Billy that he can stay with his dad.
* DoubleStandard: Works against Ted in court, with the tendency of family court to assign custody to the mother in custody battles.
* EstablishingCharacterMoment: How removed is Ted from his family's life? When he has to take Billy to school the morning after Joanna leaves, he doesn't even know what grade Billy's in.
* HandOrObjectUnderwear: See NakedPeopleAreFunny below.
* HollywoodLaw: Ted's fear of Billy having to testify if he appeals is ridiculous, considering that an appeals court does not hear new evidence, and ''nobody'' testifies as a witness.
* INeedAFreakingDrink: After Billy's temper tantrum and a nasty argument, Ted goes to the liquor cabinet and throws back some whiskey.
* JustFriends: Ted and Margaret, as Ted tells Billy directly. Any thoughts of a MaybeEverAfter ending are quashed late in the film when Margaret tells Ted she's getting back together with her ex-husband.
* LeavingYouToFindMyself: Deconstructed. Joanna leaves Ted not out of a vague desire to be a more complete person, but because all her life she's been looked after (by her family, in college) and now that she's married to Ted, he's a workaholic who leaves the entire business of raising Billy and looking after their house to her. She feels totally overwhelmed, doesn't love Ted any more, considers herself to be a terrible parent, and explicit tells Ted that Billy is "better off without me". [[spoiler: That this is not just self-justification on her part is demonstrated when, after she's been awarded custody, she decides that Billy really is better off living with Ted, and decides not to take custody of him.]]
** Reinforced later on when Billy asks Ted why his mom left, and while Ted could blame Joanna for leaving, he instead tells Billy that he himself tried to make Joanna into someone else and was too selfish to listen to her when she tried to protest, and that she left not because she doesn't love Billy, but because she can't stand Ted.
* MarriedToTheJob: Ted, or as he likes to call it, bringing home the bacon.
* MenCantKeepHouse: When Ted first tries to cook for Billy after Joanna leaves. Averted for the rest of the film.
* NakedPeopleAreFunny: After Ted brings his coworker Phyllis home for a one-night stand, she encounters Billy in the hallway, having neglected to throw a robe on for her trip to the bathroom.
-->'''Phyllis''': [''walking naked into the hall while whispering to Ted''] It's just that these morons are violating the FTC regulations so I have to get down there and make sure-- [''turns and sees Billy''] AHH!! [''[[HandOrObjectUnderwear covers her boobs and groin with her hands]]'']
-->'''Billy''': Hi.
-->'''Phyllis''': ...Hi.
-->'''Billy''': What's your name?
-->'''Phyllis''': I'm Phyllis Bernard.
-->'''Billy''': Who?
-->'''Phyllis''': I'm a f-friend of, business associate of your father's. Father. Dad.

-->'''Billy''': So do I.\\
[''Awkward pause'']
-->'''Phyllis''': Ah... Well, I, it's been really... [''starts backing away from towards the bedroom again''] It's been really nice seeing you, and, ah--
-->'''Billy''': [''going into the bathroom''] Bye.
-->'''Phyllis''': I'm...bye. [''backs into bedroom. Pause.''] Kramer. I just met your son.
* PrecisionFStrike: "Damn her!" It's only a mild one [[ItMakesSenseInContext out of context.]]
* PublicDomainSoundtrack: Vivaldi's Concerto in C major for mandolin and strings appears over the opening credits, while several Henry Purcell pieces are employed through the rest of the film.
* ShoutOut: Dustin Hoffman reads the ''Franchise/{{Tintin}}'' book ''Red Rackham's Treasure'' to his son.
* TakingTheKids: Joanna wants to.
* VersusTitle
* VetinariJobSecurity: Ted, who is desperate for a new job, gets hired by telling his prospective boss that this is a one day offer.
