"And don't you think I understand what you're doing? You're trying to move him into the country... and you're keeping him away from me. And you're playing happy family. Aren't you? [begins to slice her own leg with a butcher knife] You wouldn't understand that because you're so... so selfish. He told me about you. He told me about you. He was very honest. If you weren't so stupid, you'd know that. But you're so stupid. You're so stupid... you're a stupid, selfish bitch!"
This is the whole plot of Misery. Kathy Bates won a very well-awarded Oscar for her portrayal of an obsessed fan of a male writer.
Lola from The Loved Ones kidnaps a boy she has a crush on and tortures him to have her ideal prom night. It appears to be even more twisted though, as she has unresolved sexual feelings for her father while she fiercely hates her catatonic mother.
Mark Wahlberg's character David McCall in the 1996 movie Fear has this for Nicole (Reese Witherspoon). He becomes so obsessed with her that he beats up a male friend at her school for even talking to her, manipulates her to resent her protective father while sexually abusing her female friend behind her back, carves her name into his chest, and near the end of the movie tries to invade her family's home with his friends and starts by cutting off her dog's head.
In The Crush, Adrian loves Nick so much she's willing to kill his girlfriend and her own friend to get him. Luckily, she doesn't succeed.
Many, many "evil men" in these Lifetime Movies are portrayed as evil Yanderes who ruin the lives of the "poor little women" because they won't "submit" to their cocks EVER. Remember, ladies, you should never ever trust anyone with a penis if you live in a Lifetime-like environment!
And if the Yandere is a female, she's either the Psycho Ex-Girlfriend who Wants Her Man Back NOW, or the angry Woman Scorned who wants to steal the male lead from under the female lead's nose and won't take no for an answer. Sandy Burrow (Joely Fisher) from Seduction in a Small Town is a great example of a Lifetime-like Yandere: when she throws herself at Paul Jenks (Dennis Weaver) and is rebuffed because he's Happily Married to Sarah (Melissa Gilbert), among other things, she gets so pissed that she falsely accuses them both of being horrible Abusive Parents to their two kids and gets them thrown in jail. Twice.
Cal Hockley in the 1997 movie Titanic. He became increasingly possessive and violent towards his fiance Rose, and jealous of Jack, when Jack and Rose started spending a lot of time together. He had Lovejoy, his right hand man, outright stalk Rose to keep an eye on her and make sure she was not with Jack. He even framed Jack with robbery and made it so that he would be locked up in the ship's lower deck, knowing full well that the ship was sinking, and when that didn't work, tried to kill both Jack and Rose out of anger. (Though a deleted scene showed that he had Lovejoy go after Jack, wanting to have him kill Jack in his place.) Despite all that, he tried to find Rose later on, when they were both on one of the rescue ships, hoping to apologize, still wanting to marry her.
Eve Harrington from All About Eve pretends to be like this. She's the sweetest, humblest, most helpful young woman you'll ever meet, and above all else, wants to work entirely for and with Margo and model her life on Margo's, as closely as she can manage. Heaven help anyone who stands in the way of these things.
Glenn Close as Alex Forrest in Fatal Attraction. The main character's fling with her was supposed to be a one-night stand, but Alex simply would not let go, and the further he tried to distance himself from her, the crazier she got until she eventually went off the deep end. Her most infamous act gave rise to the slang term "bunny-boiler" to refer to yandere-types in the West. Glenn Close as the Yandere was one of the reasons that Fatal Attraction was popular in Japan. Not for nothing is Alex Forrest ranked #7 on AFI' s "Villains" List.
Before Fatal Attraction stole its iconic status, Clint Eastwood's Play Misty for Me was the reference movie for this trope. Eastwood's first directorial effort has him stalked by an obsessive fan. Who can frighten even Dirty Harry and The Man With No Name? Why, it's Jessica Walter (before she played the rich, alcoholic harpy Lucille onArrested Development), a veteran TV actress normally so square you would expect her to wear a shoulder strap purse and sensible skirt in the shower or on the moon. The psychotically jealous Evelyn Draper was the performance of a lifetime for her, leading a generation to get creeped out whenever they heard the classic Erroll Garner tune on the radio.
In the 2007 film adaptation of Sweeney Todd: The Demon Barber of Fleet Street, Mrs. Nellie Lovett spends the movie jumping between swooning over her beloved "Mr. T" and gladly butchering his victims to make pie. This is consistent with her behavior in the stage musical. The yandere-ness, on the other hand, comes in with her treatment of Lucy Barker, a.k.a. the Beggar Woman, and the way that she led Sweeney to believe that she was dead so that she could have him for herself.
In Audition, the male lead holds an audition for a girlfriend/wife under the guise of an audition for a movie, only to have the girl he picks be Asami... a very, very creepy yandere. One scene involves the girl putting needles in the victim's eyes, all the while making an almost cutesy sound while gently (agonizingly) taping them in. In short, she tortures him for misleading her into believing he would love only her, not for the fake movie audition. Very, very creepy.
The aptly-titled film Obsessed centers around this trope.
The main plot of another film titled Obsessed is Idris Elba's main character in a Psychotic Love Triangle with the woman he had an affair with and his wife. Now while this may sound hot to some many others would be praying for the sweet release of death from this scenario.
Debbie Jellinsky from Addams Family Values, who earned the nickname "Black Widow" for murdering husbands who were too busy to give her the love she needed (it doesn't help that she, being a materialistic woman, likes to marry men who have a lot of money, who usually have to work around the clock).
Debbie : Sorry, Debbie, no Mercedes this year. We have to set an example. Oh yeah? Set this!
The Flying Brick title character of My Super Ex-Girlfriend (Uma Thurman) vows to destroy the protagonist's life after he breaks up with her. One memorable scene had her throw a shark into the bedroom of his new girlfriend after spending the night with her.
In a subversion, this is because all of her previous husbands abandoned her and she's developed a complex — or so she thinks. Turns out Harriet's sister was an insane Yandere for Harriet. She murdered Harriet's husbands and faked their 'Dear Jane' notes to keep Harriet to herself and nearly does the same to Charlie near the end.
Liz Dunn from the British movie The Hole, who locks herself, her best friend, the guy she fancies and his best friend in the bunker in order to get the guy to notice her. She won't stop even when the situation deteriorates.
The French film He Loves Me... He Loves Me Not (À la folie... pas du tout) is about a young woman who at first appears to be in a relationship with an emotionally distant doctor, until the second half, when it turns out that he didn't know her at all.
In The Snake Pit, the insane asylum's head nurse is one of these, getting jealous because she believes the main character is competition for Dr. Kik's affections. It should be added that there's absolutely no good reason to believe that Dr. Kik feels anything more than what he ought to for her, especially given that his goal is to get her well enough to leave with her husband.
In the movie Rat Race Tracy goes into psycho mode when she finds her boyfriend cheating on her with his ex. Upon seeing him and his ex in a steamy pool in the backyard, she attempts to nose dive at them in her helicopter and in their haste to avoid it they break the pool and the water sends them crashing into the side of his house. After that, she proceeds to drop things, including a can of pink paint, onto his truck, and chase him down in the chopper, while using the landing skids to destroy his truck. After running him off the road, she steals the truck upon finding her helicopter's engine is shot. She then yells and punches him in the face, almost strangles him with the truck window, puts a bra in his mouth and throws him out of the already running truck.
In the French film Haute Tension, this trope is exemplified in the protagonist, Marie, who creates an alternate personality to brutally murder the family of her lesbian crush, Alex... simply so that she could have her all to herself.
The Other Mother in the film-adaptation of Coraline. So much...
DON'T LEAVE ME! DON'T LEAVE MEEEE! I'LL DIE, I'LL DIE WITHOUT YOOOOUUU!"
Mal Cobb in Inception. While both alive and in her husband's subconcious. Although, she's in this state because her husband Mind Raped her into it, leaving us to wonder who the real yandere is here.
It's made explicit that the reason she's there is that Cobb can't let her go even though she's crazy, dead, and a serious danger to everyone, so this trope applies to both of them.
Princess Kaede in Ran behaves like a yandere in many ways, but it's all (or at least mostly) an act. That is, the part in which she is madly in love with Jiro. The part in which she orders all competition killed and wants to murder him is real however.
In Tormented we get a yandere ghost. Disturbingly, the movie seems to consider her actions, and her perception of events, as perfectly justified.
Star Wars: Anakin Skywalker lives this trope. He falls in love with exactly one girl, Padme Amidala, in his whole life, and they go from "old crush" to "man and wife" in the course of Attack of the Clones. Then he thinks she'll die in childbirth during Revenge of the Sith, so he makes his Face-Heel Turn to The Dark Side to prevent it...and then he Force Choke her to near death (she later dies on the medical table after her childbirth) because he got it into his head that she betrayed him for Obi-Wan Kenobi, whom he saw as competition even though he really wasn't.
Christy Lee in The Social Network, to a lesser extent. Intentionally setting your boyfriend's bed on fire is normal, right?
The Lifetime Original Movie Homecoming is one, with a plot somewhat similar to Misery. One of the few instances where the film is built around the torturing of her "beloved's" romantic interests.
Jackson Rippner in Red Eye to Lisa. Confirmed by Word of God in the commentary, Rippner did develop feelings for Lisa over the eight weeks he had to watch her. Not healthy feelings, but feelings nevertheless.
In The Adventures Of Tom Thumb and Thumbelina the Mole King goes Ax-Crazy when Thumbelina rejects him and chooses Tom instead.
In Villain, when the Villain Protagonist Shimizu's girlfriend stands him up to go off with another guy, Shimizu follows them and kills her.
Blue in Sucker Punch is a definitive male version of this trope: creepy, violent, possessive, moody, delusional, obsessive, creepy, mood swingy, twisted sense of ownership, disrespectful, and insane.
Lost Highway. Mr Eddy: Her name is Alice. I swear I love that girl to death. If I ever found out someone was making out with her, I'd take this - pulls out a pistol - and shove it so far up his ass it would come out his mouth. Then you know what I'd do? I'd blow his fuckin' brains out.
Angelique in Dark Shadows. Dear God, Angelique. It's not enough to simply kill the parents of the man who spurned you, to really get his heart you apparently have to kill his girlfriend, turn him into a vampire so he can never die, then lock him in an iron box so that he's left to suffer for eternity, as well as curse his descendants.
Edward Nygma (a.k.a. the Riddler) of Batman Forever seems an awful lot like one of the male persuasion. He keeps pictures of Bruce Wayne on his desk (glamour shots from a ladies' magazine, yet), gets nervous and giggly when meeting Wayne for the first time as well as spouting unnerving phrases of devotion and insisting that Wayne accept his opus... and tipping completely off the deep end immediately after having his plan nixed by Bruce.
Lifetime Movie: Maternal Obsession (formerly titled Her Only Child) which features mother, Inez, having this for her own daughter, Lily. She does everything to sabotage her child's relationship with Larry, the current love interest. Even going as far to cut herself and making the family dog sick. The daughter confronts her mother about her behavior and finds that she sabotaged other relationships by hiring thugs to beat up an ex-boyfriend, Michael. At some point Inez pulls a gun on Larry and then threatens to kill herself.
Jareth for Sarah in Labyrinth. He claims that he has done a lot of things to please Sarah, including taking her half-brother away like she wished for, and he calls her out on being "selfish". The truth, though, is that Sarah didn't know he really existed until he revealed himself to her and she doesn't know about the other wishes he's "granted". At one point, he expressed a hint of jealousy towards Hoggle and threatened to banish him to the Bog of Eternal Stench if Sarah kissed him.
In No Brother of Mine, Drew is willing to do anything for his older sister. He would kill if it means protecting her.
In Queen of the Damned Akasha develops an attraction to Lestat after being taken with him when he plays the violin for her and allows him to drink her blood. After she wakes up centuries later she murders anyone who might prove a threat to Lestat and kidnaps him at his concert to have him for herself. She also killed her previous husband by ripping out his throat to make herself available, orders Lestat to murder Jesse to prove his love for her and tries to kill him without a second thought when he refuses.
Victor Creed towards Logan in X-Men Origins: Wolverine, it's about a sibling relationship and not lovers, but it fits pretty well.
