Played with in My Super Ex-Girlfriend a romantic comedy about a guy, who in response to him leaving his super-powered girlfriend for being crazy, she proceeds to do all sorts of vicious things, ranging from throwing his car onto the moon, get him fired by using her powers to strip him naked in the office, and throwing a shark at him. Though it's played for laughs, we still seem intended to sympathize with the guy. Once people realize both that it's G-Girl who's after him and that she's angry over the breakup rather than trying to capture him for some undisclosed crime, they get a lot more upset with her, and she wasn't quite a Karma Houdini either, she is briefly Brought Down to Normal in a plot to stop her tirade, when she refuses to let it go even after that, the guy's current (much less unhinged) girlfriend uses her new found powers to beat some sense into her.
Still played straight in that this movie couldn't possibly work as a comedy if the gender roles were reversed and the super ex-boyfriend did the same things.
Played straight in Nick and Norah's Infinite Playlist when the titular characters are arguing and Norah gets so upset that she hits Nick in the throat. The double standard is particularly striking, considering that Michael Cera (Nick) has the build of a twelve year old girl, making Kat Dennings (Nora) looks like an Olympic powerlifter compared to him. There's also the fact that Nick was getting over a break-up with Tris, who emotionally abuses him.
In Kung Fu Hustle, the domineering landlady constantly beats on her lecherous doormat of a husband with comedic, slapstick violence. It's apparently justified midway through the film when it's revealed that his martial arts specialty is to absorb tremendous punishment without any harm.
Tokyo Zombie includes a scene in which a meek abused man buries his mother in a giant mountain of trash and corpses at his girlfriend's instance (specifically, when threatened with sex deprivation). Not content with that the girl proceeds to kick her head into orbit while still belittling her boyfriend.
The War of the Roses is built around playing an Escalating War of domestic abuse for dark comedy. The wife is always played as far more brutal and vicious than the husband in an apparent effort to keep the two even.
In the original Parent Trap, in a fit of anger at one point Maggie socks her ex-husband Mitch in the eye. His dialogue seems to imply she'd done stuff like that back when they were married: "Why do you have to get so physical? Can't even talk to you about anything, you're always trying to belt me with something." The movie tries to make the whole situation seem cutesy by the awkward and girly way in which she throws the punch, but for the modern viewer it casts an ominous tone over their eventual reconciliation.
The remake acknowledges this in a conversation between Nick and Elizabeth, talking about one of their fights. Elizabeth asks "did I hurt you when I threw that...what was it?" and Nick coldly says "it was a hair dryer" which prompts a very guilty look from Elizabeth. Later on Meredith has thrown a ring at him and he says to Elizabeth in the same tone "at least it's smaller than a hair dryer".
Played straight in Birthday Girl. Sophia participates in the beating, robbery, torture, and kidnapping of her husband John. She gets angry at her co-conspirators later and decides to free John, but never so much as apologizes for her actions - and the fool nonetheless sticks with her and they live (happily?) ever after together. There are even disturbing intimations that John deserves to be victimized because he is a fan of bondage porn, although he never even hints at acting out his fantasies on Sophia, and he is mortally embarrassed when he realizes that she knows about his tastes, even though she implies that she regards them as harmless.
Played straight in Troll 2: Holly and Elliot's relationship would probably have been handled differently if the roles had been reversed.
More or less played straight in Baby Boy. Yvette (Taraji Henson's character), in a fit of rage, starts swinging her hands toward her boyfriend Jody (Tyrese's character). While one could certainly understand why Yvette's upset, what with Jody's constant cheating and lying, that does not excuse her violently whaling at him to the point of punching him in the eye really hard. So when Jody fought back after failing to restrain Yvette, he smacks her in self-defense, which anyone has the right to do. The movie unfairly paints Jody's actions as a Kick the Dog/Moral Event Horizon moment.
Played straight to the point of being disturbing in the romantic comedy Serious Moonlight where Meg Ryan's character knocks her cheating husband unconscious by a potted plant at his head twice and tapes him to a chair until he loves her again. Switch the genders and it becomes a lot less funny.
A scene in Skip Woods's debut film, Thursday involves the main protagonist being tied to a chair by a woman working for the film's antagonist; the woman then proceeds to rape and taunt him by saying she won't kill him until he achieves an orgasm, which he tries desperately hard to avoid, and adds that she hopes he'll get her pregnant. While the character finds the situation revolting, the scene is played for titulation.
In Think Like A Man, it's repeatedly implied that Cedric's wife is physically, verbally, and emotionally abusive to him—there are references to him having a black eye that he tries to play off as a sports injury—and that the very reason he's leaving her is because he's fed up with it. But the entire scenario is played for laughs throughout the film, with his friends constantly teasing him about it, and at the end, he goes back to her.
The 2014 comedy The Other Woman features three women tormenting a cheating man (psychologically and physically). Like many other comedies of this ilk, audiences are expected to root for the female characters despite their near-sociopathic behavior. However, it's not likely that audiences would accept a film where three men get revenge on a cheating woman by ganging up on her...even if her relationship crimes were just as heinous.
