Kathryn Hahn has always been an actress who, during a scene, makes you lean over and say, “Who is she? She’s amazing.” For years, she was the stealth MVP – going quietly into the supporting roles, stealing every scene, and having you wish she had more screen time. But in the last decade, Hahn transformed, proving that she is one of the most versatile, charismatic, and simply great actors in Hollywood. And now, with Agatha All Along bringing her to the forefront as Disney+’s reigning witch, her time has come. Here is a summary of 10 of her most unforgettable performances- the evidence that Kathryn Hahn was always magic.
10. How to Lose a Guy in 10 Days – The Rom-Com Bestie Who Stole the Show
Before the world learned her name, Hahn was acting as Michelle, the ditzy, tear-prone best friend to Kate Hudson’s Andie. She added pitch-perfect proportions of comedic sense and relatable vulnerability, making what might have been a throwaway sidekick into a character you remember.
9. Step Brothers – Comedy Chaos in Human Form
Alice, the put-together wife who loses it, is one of Hahn’s most off-the-wall and side-splitting characters. Her commitment to going all-in—physically and vocally—separated her from the comedic greats in this stacked cast.
8. Bad Moms – Carla, the PTA’s Worst Nightmare
In a film full of crazy energy, Hahn’s Carla continues to be the loudest, brashest, and most humorous presence on screen. She’s raw, unapologetic, and somehow still manages to slip in genuine heart. This role solidified Hahn as a comedic force to be reckoned with who can lead a hit.
7. Transparent – A Grounding Force
As Rabbi Raquel, Hahn replaced her typical comedic pyrotechnics with restrained elegance. Her work added warmth and nuance to the Pfefferman clan’s saga, for which she was an Emmy nominee, and proved she could be just as radiant in drama.
6. Private Life – Heartbreak with a Side of Humor
In Tamara Jenkins’ indie drama, Hahn stars as Rachel, an author struggling with infertility. It’s a richly human performance—funny here, heartbreaking there—that demonstrates Hahn’s uncommon skill with blending emotional authenticity and lightness.
5. Mrs. Fletcher – A Lead Role Worth Waiting For
HBO finally gave Hahn the spotlight with Mrs. Fletcher, and she didn’t waste a second. As Eve Fletcher, a single mom reinventing herself after her son leaves for college, Hahn is awkward, charming, and heartbreakingly real.
4. WandaVision – The Neighbor Who Wasn’t What She Seemed
Agnes appeared as your average sitcom next-door neighbor—until the now-famous moment of revelation that she was Agatha Harkness. Hahn’s transformation from sitcom sweetheart to cunning sorceress was absolute gold, topped off by a theme song that went instantly viral.
3. Spider-Man: Into the Spider-Verse – A Villainous Glow-Up
Even in cartoonish guise, Hahn’s Olivia Octavius (a wondrous, female Doc Ock) exudes personality. She’s witty, amusing, and wonderfully sinister—a wonderful illustration of how Hahn’s voice acting is as iconic as her screen presence.
2. Parks and Recreation – The Queen of Political Shade
Jennifer Barkley, the whip-smart political strategist who could talk anyone to ribbons, was among Hahn’s most tasty roles. Each episode was a combination of charm, wit, and ruthlessness that rendered her one of the show’s favorite guest stars.
1. Agatha All Along – The Crown Jewel
Now, Hahn gets to unleash Agatha Harkness in full on her Disney+ series, with a mix of horror, camp, and unapologetic weirdness. Whether sparring magical banter with Aubrey Plaza or commanding a witchy musical number, Hahn shows that she’s not just a scene-stealer, but the main attraction.
From rom-com wingwoman to Marvel’s most charismatic antihero, Kathryn Hahn has gone from “who’s that?” to “oh, she’s the reason I’m watching.” Turns out, it was Agatha all along.
