Law Of Inverse Fertility / Live-Action Films

• 2:37: Neither Melody nor her brother Marcus wanted her to get pregnant when he raped her.
• In Apocalypto, Blunt and his wife want kids, especially because Blunt's mother-in-law keeps verbally abusing him in front of the village about giving her grandkids, but just can't seem to have any. However, it's implied that the problem is not so much physical as it is Blunt preferring a sexual act that makes conception is impossible. Not that it ends up mattering, as Blunt and his wife both end up being killed by slavers.
• Apparitional: Joel and Kate have been trying to have a baby for a long time, but haven't had any luck in doing so. Some person in a diner says it's because she has phantoms inside her body preventing it from happening.
• Baby Mama. Though it should be noted that the main character is over 35 and the character with the unexpected pregnancy (well, unexpected maternity) was hired as a surrogate and had just undergone a round of fertility drugs and attempted insemination.^note The insemination didn't take, so she had sex with her husband and got pregnant the old-fashioned way.
• In Beetlejuice the one cloud in Adam and Barbara's blissful marriage is their inability to have a child. When Jane comments on how their house should be for a family Barbara looks crushed, implying that she may be having trouble conceiving. By movie's end, they've become sort-of surrogate parents to Lydia.
• Cthulhu (2007). The father of the protagonist wants his gay son to start a family; naturally, he refuses and snidely suggests pressuring his sister instead. She immediately storms off crying as she's been unable to have children. It turns out the father has his own dark reasons for continuing their line and later arranges for the protagonist to be drugged and raped by a woman to ensure this happens.
• The Curious Case of Benjamin Button, Queenie wants a child but can't have one. The only child she raises is Benjamin, who loves her and later says that Queenie is born to be a mother.
• In Das Finstere Tal the patriarch of the Brenner clan, the Big Bad, impregnated the protagonist Greider's mother while exercising Droit du Seigneur on her, and tells him so just before being killed off.
• Desperados (2020): Kaylie and her husband Tad are unable to have children, while Brooke got pregnant b her cheating husband despite not wanting kids.
• In Diary of a Mad Black Woman, Helen wanted to have children with Charles, but had two miscarriages. Meanwhile, he had two unplanned children with his mistress.
• Part of Bethany's backstory in Dogma is that her husband left her when he found out that she couldn't have kids. (Information in the script reveals that her sterility came from an earlier abortion that her husband didn't want her to have.) The movie ends with her pregnant, apparently from a supernatural conception a la the Virgin Mary.
• In Eat Drink Man Woman, Jia-Ning gets pregnant after sleeping with her boyfriend once.
• Elena Undone: Elena and Berry try unsuccessfully to have another child. At the end she's managed to via IVF with another man's sperm after they divorced.
• The trope is played very straight with The Flintstones, in the film as well as the cartoon. The difference is that in the film, the Rubbles decide to adopt, and Fred empties his savings account to lend them the money so they can afford to do so.
• For Colored Girls: Kelly, with her husband, finds out that she can't have children since her fallopian tubes are scarred from an STD. Nyla meanwhile gets pregnant accidentally from having casual sex.
• In For Keeps, it apparently only took one wild weekend for Stan and Darcy to conceive, and they were definitely not looking to have a child at that time.
• Freshman Year: CJ gets Marcella pregnant when it was both unplanned and the first time both had sex.
• In Hannah and Her Sisters, Mickey is told he is infertile. He and his wife Hannah have twins via in-vitro fertilization and a sperm donation from a family friend. Years later, Mickey marries Holly and she surprises him at Thanksgiving by telling him that she's pregnant.
• Holly Slept Over: Audra and Noel have been trying to get pregnant for a year without success. It turns out Audra got pregnant easily in high school though, but didn't want to tell Noel as she worried he would blame himself. He'd gotten his sperm tested however, with them being fine, so he concludes neither is infertile they just didn't manage to conceive yet.
• The introduction to Idiocracy features a highly intelligent couple who want to have a baby but keep putting it off for various reasons (not ready; not settled; husband's infertile; husband's dead; husband's frozen sperm melted in an accident...) while dumb white trash Clevon has a continually growing family tree. Particularly funny when Clevon gets into a crotch-related accident, but still has a dozen more kids after that.
• In The Inner Circle, Anastasya desperately wants to have a child with her husband Ivan, but continually fails to conceive. However, she then gets pregnant very easily when Beria takes her as a mistress, with her consent being very dubious in the whole situation.
• In Instant Family, Ellie's younger sister has been trying to get pregnant for years, with her husband making snarky comments about her desire to try fertility treatments. Ellie and Pete never tried conception, but eventually decide to take in three foster children, making them parents first. Ellie's sister then says that her example has inspired her and her husband to adopt as well (not only because it's cheaper, but that is a factor). The last scene of the movie is Ellie and Pete officially adopting Lizzie, Juan, and Lita, and the sister is in the audience holding hands with a young boy she's presumably fostering... while she's visibly pregnant.
• In Johnny Belinda, Belinda gets pregnant after her first time, which was also rape.
• Handled with wonderful subtlety in the film Julie & Julia. At one point near the beginning, Julia gives a woman passing by with a stroller a longing look; later in the film, she gets a letter informing her that her sister is pregnant, and while she tries to express joy she can't help bursting into tears instead. That's all we get on the matter.
• The whole point of the movies Juno, Knocked Up, Waitress, Saved!, and going back a bit further, Maybe Baby.
• In the dark comedy Kingdom Come, Luanne's angst comes from her inability to have children. She had multiple miscarriages, her latest one lost in an empty fried chicken bucket (she was ordered on bed rest and was using it as a makeshift bedpan while her husband Ray went to the drug store to buy a real one; a KFC bucket then a triggers bad memories for her). She and Ray stopped trying after that. Towards the end of the movie, she discovers that she's pregnant again, and the "Where Are They Now?" Epilogue over the end credits show her and Ray with a baby girl.
• Lady Macbeth: A catalyst for Katherine's murder of Teddy. After discovering that she is unexpectedly pregnant with Sebastian's child, she tries to tell him, but he's angry at being forced to sleep in the stable because of Teddy's presence and sends her away. This begins a series of events which ends up with Katherine smothering Teddy with a pillow.
• In the second Look Who's Talking film, Mollie gets pregnant with Jimmy's daughter and Mikey's half-sister, Julie, despite wearing her diaphragm. The diaphragm is also a Chekhov's Gun from the first film. Justified as an example of Truth in Television because diaphragms are not as reliable as other methods of birth control.
• Love Is Not Perfect: Shortly after expressing her lack of desire for motherhood (her boyfriend wants a child) Elena gets accidentally pregnant.
• Love, Rosie: Rosie and Greg certainly weren't planning to conceive (they used a condom), but she became pregnant by accident due to a mishap with it.
• In Match Point, Villain Protagonist Chris Wilton has trouble conceiving with his wife, but knocks up his mistress pretty much immediately, the irony of which he notes ruefully. After killing the mistress to keep things quiet, his wife finally gets pregnant.
• Miss Meadows: Miss Meadows gets pregnant due to a single time having sex with Mike, without intending to. She decides to have the baby.
• A New York Christmas Wedding: Gabby got pregnant unintentionally the very first time she slept with a guy, her boyfriend.

• George knocks up Alice after one encounter in A Place in the Sun. This is disastrous, as not only will it lose him his job (fraternization is forbidden at the factory), it will kill his budding romance with gorgeous, rich society girl Angela and eventually leads to the demise of both George and Alice.
• Dr. Elizabeth Shaw from Prometheus is unable to conceive a child, and late one night gets freaky with her husband after he has been unknowingly infected with an alien mutagen. She ends up conceiving, but the child... well, cross Starfish Alien with Enfant Terrible and you've got a start.
• Raising Arizona uses this as the crux of its plot, where a married couple can neither conceive (because the wife is infertile) nor adopt (because the husband has a shaky, criminal history), so instead they opt to kidnap one of the recently-born Arizona quintuplets, since the father was quoted in the media as saying they had more children than they could handle.
  • This particularly fits the trope because the wife is absolutely desperate to have a child. When she finds out she can't, she's so depressed she quits the police force.
• Revenge of the Sith : Somehow, despite living on an incredibly high tech planet with presumably plenty of access to effective birth control, and considering that having children would be a dead giveaway to her secret marriage to a Jedi Knight, Padmé still manages to get pregnant without planning to.
• The Ring: In the American remake, Richard and Anna Morgan desperately wanted to have a child, but they never could, even after years of attempt. Then they left the island and came back with Samara. They told everyone that the child was adopted, but when things began to happen, people accused them of delving into shady things to get Samara. Eventually, Richard disowned her, while Anna resorted to kill her, which drove her insane to the point of suicide.
• School Waltz: Zolya sneaks Gosha into her family's apartment for some post-graduation sex. Naturally, she turns up pregnant. A shocked Gosha dumps her.
• Secrets & Lies: Cynthia had two unplanned pregnancies, while Maurice and Monica tried to have kids for 15 years with no success.
• Claudia desperately wants a child in Snow White: A Tale of Terror, but she only carries to term/gets pregnant (the film doesn't specify which) one time in nine years. The baby doesn't live.
• Something Wicked: Susan and Bill are trying to start a family, but she can't get pregnant, which causes a rift in their marriage.
• The Terrorist: Malli gets pregnant by having sex with a fellow cadre just once without meaning to (for bonus points, it's right before he dies)
• A subplot in This Is Where I Leave You is Paul and Annie's inscreasingly desperate but unsuccessful attempts to have a baby, while Judd finds out that Quinn, who he's in the process of divorcing, is pregnant with his child. This makes Annie even more insecure and desperate about not being able to conceive, though she eventually gets over it.
• What to Expect When You're Expecting:
  • After deciding to take a break from years of trying to conceive, one of the couples conceives during a drunken romp in the bushes. Keep in mind that she was drinking because they had decided to take a break and therefore she no longer needed to abstain from alcohol. They are a little annoyed when his father and his younger wife managed to get pregnant with no trouble at all.
  • Surprisingly averted with another couple who has struggled with infertility for years and finally decided to adopt. At no time does she finally conceive naturally.
  • Two women get pregnant accidentally, one with her new boyfriend and one during a one night stand. The latter was heartbroken when she lost her child due to miscarriage.
• Where Are My Children?: Poor Lillian gets knocked up after having sex once, much to her horror. Mrs. Walton aborts three pregnancies, only to find when she changes her mind that those abortions robbed her of the chance to have any other children.
• Women Is Losers: Celina gets pregnant by Mateo unintentionally, in what's also her first time.
• In Written on the Wind, Kyle really wants children, so naturally he has fertility problems. When Lucy eventually gets pregnant, he's unsure whether he's really the father, and when he subsequently hits her in a jealous rage, she has a miscarriage.
