The evidence supports several sitcom cast tensions, but not 15 distinct, well-documented cases. The examples below separate serious incidents and firsthand accounts from allegations, creative mismatches, and conflicts that began outside the show. They do not all amount to mutual hatred.
Serious on-set incidents and workplace conflict
Jessica Walter and Jeffrey Tambor on Arrested Development
During a 2018 cast interview, Walter said Tambor had yelled at and verbally harassed her during an on-set incident. “In like almost 60 years of working, I’ve never had anybody yell at me like that on a set,” she said. Tambor apologized, and Walter also said she had moved on. Her account documents a serious incident; it does not establish that the two mutually hated each other. TIME reported the interview and its context.

Martin Lawrence and Tisha Campbell on Martin
Campbell left during the sitcom’s final season and sued Lawrence, alleging sexual harassment and verbal abuse. The suit settled out of court; a settlement is not an adjudicated finding that the allegations were true. Campbell later returned for two episodes on the condition that she and Lawrence not share scenes. They reunited for a 2022 special. TVLine recounts the dispute and later appearances.
Ed O’Neill and Amanda Bearse on Married… With Children
O’Neill recalled a major argument with Bearse in front of the cast and crew. He said she called him a bully and that he responded by saying he had the power to get her removed. He also said he did not use that power; Bearse stayed for the show’s 11-season run. The story is about personal friction and an imbalance of workplace power, not proof that one actor actually had the other dismissed. TVLine summarizes O’Neill’s account.

Departures and disputes with more than one explanation
Will Smith and Janet Hubert on The Fresh Prince of Bel-Air
Hubert left after season three amid a contract dispute and conflict with Smith. Smith later acknowledged that he had made the set difficult for her, and the two reunited in 2020. The departure should not be reduced to a single cause or a simple story of one person being solely at fault. TVLine reports the conflict and reunion.
Charlie Sheen and Selma Blair on Anger Management
TVLine recounts reports that Blair complained about Sheen’s work ethic and that he allegedly refused to shoot with her before she left the series. That is a reported account, not enough to state as settled fact that Sheen personally fired her. TVLine’s roundup describes the reports.
Long-running friction and conflicting memories
Betty White and Bea Arthur on The Golden Girls
White said Arthur “was not that fond of me” and sometimes found her “a pain in the neck.” Rue McClanahan wrote that their relationship was not what she wished it could be, but that it never interfered with their work. In 2025, co-producer Marsha Posner Williams described pronounced antipathy off camera; another crew member recalled more amicable behavior, and White also spoke affectionately of Arthur. Taken together, the accounts suggest friction, but they do not support a single, uncontested version of the relationship. TV Insider reports the producer’s recollections and other perspectives.
Creative tension is not the same as a feud
Jason Alexander and Heidi Swedberg on Seinfeld
Alexander said he struggled to find a way to play off Swedberg because their comic instincts did not mesh. He later apologized for telling the story in a way that might diminish her. This describes a performance mismatch as Alexander experienced it, not evidence that the co-stars hated each other. TVLine recounts his comments and apology.

Rank #3
Neil Patrick Harris and Josh Radnor on How I Met Your Mother
Harris said he sometimes sensed that Radnor was frustrated when Harris concentrated on comic bits while Radnor focused on emotional beats. “I always kind of felt that my performance annoyed you, Josh,” Harris said in a podcast conversation. Radnor suggested they had blurred actor and character together and described their chemistry positively. Their comments point to different approaches to a scene, not a confirmed feud. CinemaBlend reports the conversation.
Early friction that did not define the whole relationship
John Stamos and Bob Saget on Full House
In his memoir, Stamos described doubts about Saget’s casting and wanting to leave after the first table read. He also characterized their relationship in prickly but affectionate terms, and they later worked together again. The account suggests early friction and contrasting styles rather than sustained enmity. TVLine summarizes Stamos’s recollections.
Rank #4
Lea Michele and Naya Rivera on Glee
Rivera wrote that she and Michele could get heated and that Michele did not like sharing the spotlight. Rivera explicitly said she did not hate Michele. That qualification matters: Rivera’s description supports tension and competition, not a claim of mutual hatred. TVLine summarizes Rivera’s account.

Anthony Anderson and Tracee Ellis Ross on black-ish
Anderson said Ross did not like him for years after he joked at her expense while co-hosting an awards show in 2005. He said they reconciled during the first season of black-ish. Since the reported source of the conflict predates the sitcom, it is not accurate to present this as an on-set feud. TV Insider includes Anderson’s account.
Best Value
Bruce Willis and Cybill Shepherd on Moonlighting
Shepherd said that at one point she and Willis hated each other, and co-star Allyce Beasley recalled that they were unhappy and difficult to be around. They later looked back fondly and worked together on DVD commentaries. However, Moonlighting is generally described as a comedy-drama, not straightforwardly a sitcom, so it is a borderline fit for a strictly sitcom-only list. TVLine reports the recollections and later cooperation.
Quick Recap
How to read stories about co-stars who clashed
- Separate a firsthand account from a proven finding. Walter’s description of being yelled at is her account of an incident; Campbell’s lawsuit contained allegations that settled out of court.
- Keep the scale of the claim intact. A disagreement about performance, an awkward dynamic, and a sustained personal feud are different things.
- Include what happened later. Apologies, reunions, continued work, and reconciliations can complicate the idea that a conflict defined the relationship.
- Check whether the conflict belongs to the show. Anderson and Ross’s reported disagreement began before black-ish; their story is not evidence of an on-set feud.
