Something's Gotta Give
Harry Sanborn (Jack Nicholson) is a wealthy New York music mogul who has had a 40 year-long habit of dating women under 30. When he and his latest conquest, Marin Klein (Amanda Peet), drive to her mother's Hamptons beach house on the coast, his life turns upside down.
Expecting to be alone, Harry and Marin are surprised by Marin's mother, successful playwright Erica Barry (Diane Keaton), and her sister Zoe (Frances McDormand). After an awkward dinner, the night turns disastrous when — during foreplay with Marin — Harry has a heart attack and is rushed to a hospital. The handsome young doctor, Julian Mercer (Keanu Reeves), tells Harry to stay in the area for a few days, and so Harry ends up staying with Erica, Zoe and Marin both having to go back to the city. Harry and Erica's differing personalities initially make for awkward living arrangements (including a memorable scene where Harry accidentally sees Erica naked), until the two begin to get to know each other.
Soon, they start to get along, although they live very different lifestyles — Erica's determination to be single and independent, and Harry's constant desire for new women and experiences — combined with the fact that Harry is dating Marin and Julian has fallen for Erica, leave the two struggling to deal with their current relationships with others, but also work on their own. Marin soon breaks up with Harry after she suspects that he's in love with her mother. The break up is not out of anger, but rather she wants her mother to be able to have a relationship with him and for her own life to move on. Harry, however, has apparently made the same decision, and they break up with each other simultaneously. Harry and Erica spend more time together and the relationship they have with each other gets even more serious. After they have sex, Harry discovers that his improving health means that he no longer has to stay with Erica, and in a very awkward decision, he heads home.
Meanwhile, Marin receives news that her father, Erica's ex-husband whom she still allows to direct her plays, is getting remarried. Although Erica is unaffected by the news, Marin is devastated, exhibiting self-centered behavior which implies that she is the only one this concerns. She pressures her mother into going to dinner with Marin to see her ex-husband and his new fiancée. At dinner, Erica is the life of the party until she sees Harry at another table with another woman (Tayrene Mugridge), and is crushed, because she realizes that she still loves him. Harry spots Erica and tries to convince her that the woman was just a friend and that they weren't in a relationship. In the argument that follows, Harry suffers from what he believes is another heart attack and is rushed to the hospital where he is told that it is only a panic attack but he must rest if he doesn't want to end up in the hospital every week. The female doctor, Dr. Martinez (Rachel Ticotin), tells him that if he was her 'Dad' she would not want him out alone so soon after a heart attack, clearly emphasizing his age. Harry goes home in an attempt to get some rest.
Erica, on the other hand, also goes back home and breaks down into tears. Although she is heartbroken, she figures that the events that are happening in her own life would be great to use in a play, and thus she starts to write a play on the whole experience. While at lunch with a friend, presumably an actress, Harry hears her ramble about a new play for which she is auditioning; she begins to summarize it, while explaining how funny it is. Harry nearly chokes when he realizes the play is about him and rushes to the stage where it is being rehearsed, and sees Erica. They don't manage to heal the wounds that have been made and Erica tells Harry to get on with life.
Harry visits Marin six months later, who tells him that she is pregnant and has a new husband. Harry apologizes if he ever hurt her and she tells him that was never the case. She also tells him that her mother is in Paris to celebrate her birthday. Harry shows up at the restaurant where she is eating because of an agreement they made earlier, that they'd spend their birthdays (Erica in January, Harry in February) together in Paris. Harry tells Erica that he has spent the last six months making things right with all his former women friends.
She was waiting for Julian, whom she met when Harry had his first episode. Harry and Erica are extremely happy to see each other and once again realize how much they are in love. Julian interrupts when he enters the restaurant a little late. They never have time to really tell each other their true feelings until hours after the dinner, when Erica says goodbye outside the restaurant to Harry.
While Harry is gazing over the river Seine in the Paris night saying "look who gets to be the girl" as it starts to snow, Erica pulls up in a taxi. She gets out and explains to Harry that Julian figured that they both still loved each other. Harry says "I'm 63 years old and for the first time in love." Harry and Erica kiss; the movie resumes about 1-1/2 years later, at another restaurant in New York. Erica and Harry, now married, are eating out with Marin and her new husband with their year old child.
