1. Promising Young Woman (2020)
Emerald Fennell's electrifying debut is a blistering, candy-coated revenge fantasy that tackles trauma with a confrontational smirk. Its protagonist, Cassie, uses her wits to expose the hypocrisy of so-called "nice guys." This mirrors Joan Rivers' own
comedic strategy: using a glamorous, feminine presentation to deliver brutally honest and often uncomfortable truths. Rivers famously said that comedy is about telling the truth, and Cassie's quest, while dark, is a relentless pursuit of a certain kind of truth, forcing people to see a reality they'd rather ignore. The film's blend of scathing social commentary with a pop-forward aesthetic feels like a direct descendant of Rivers' ability to critique culture while being a fabulous part of it.
2. Young Adult (2011)
Charlize Theron's Mavis Gary is a masterpiece of an unlikable protagonist. She's a ghostwriter for a teen book series who returns to her hometown to reclaim her glory days by winning back her now-married high school boyfriend. The film, penned by Diablo Cody, is celebrated for its razor-sharp and acid-tongued dialogue. Mavis is delusional, selfish, and often drunk, but she's also tragically, hilariously human. Her refusal to apologize for her messy, complicated desires is pure Rivers. Joan built a career on self-deprecation that doubled as a weapon, and Mavis embodies that same spirit of a woman who is deeply flawed and utterly unwilling to ask for your sympathy.
3. Heathers (1989)
Before dark comedy was a mainstream genre, there was Heathers. This landmark satire, which follows a high school girl and her sociopathic boyfriend as they murder popular students and disguise them as suicides, was shocking for its time. Its cynical, whip-smart dialogue changed the game for teen movies, moving away from the earnestness of John Hughes and into something far more dangerous and biting. This is the cinematic equivalent of Rivers crashing the 1980s party. Her comedy was always about pushing boundaries and saying the things you're not supposed to say out loud. Heathers does just that, using its outrageous plot and quotable one-liners to expose the brutal absurdity of high school social structures.
4. I, Tonya (2017)
This darkly comedic biopic reframes the story of vilified figure skater Tonya Harding, not as a simple villain, but as a defiant outsider crushed by a system that demanded a certain kind of wholesome femininity she couldn't—and wouldn't—provide. The film constantly breaks the fourth wall, with Margot Robbie's Tonya speaking directly to the audience, controlling her own narrative in a way the real Harding never could. This act of reclamation is central to the Joan Rivers legacy. After her falling out with Johnny Carson and the cancellation of her late-night show, Rivers had to constantly reinvent herself to stay relevant, fighting for every inch of her career. I, Tonya captures that same scrappy, defiant energy of a talented, working-class woman who refuses to be erased.
5. Ghost World (2001)
Based on Daniel Clowes' graphic novel, Ghost World is the anthem for the proudly cynical. Its protagonist, Enid, played to deadpan perfection by Thora Birch, navigates the post-high school void by casting a judgmental, witty eye on the vapid consumer culture and suburban weirdos surrounding her. Her humor is a defense mechanism, a way to feel superior to a world she feels alienated from. This outsider's perspective was the bedrock of Joan Rivers' comedy. From her earliest days, she was the one on the outside looking in, using her sharp observations to comment on the absurdity of social norms, celebrity, and life itself. Enid's bone-dry wit and terminally unimpressed attitude feel like a direct spiritual inheritance.
