David Cassidy & Jeremy Gelbwaks (The Partridge Family)
Bill Moyers & Morley Safer (60 Minutes)
For the esteemed news journalists Bill Moyer and Morley Safer there were rumors of ongoing issues. Moyers claimed that Safer disliked him as early as Moyer’s stint as President Lyndon Johnson’s press secretary. Moyers further claimed that it was because of Mike Wallace that he left the show.
In his memoir, Flashbacks, Safer wrote that Moyers sat in on a meeting with Johnson and CBS president Frank Stanton in which ''Johnson threatened that, unless CBS got rid of me and 'cleaned up its act,' the White House would 'go public' with information about my 'Communist ties.'" For Moyers to be party to such a smear, Safer said, undercut his standing as ''the sometimes overly pious public defender of liberal virtue, the First Amendment and rights of minorities.''
Melissa Gilbert & Dean Butler (Little House on the Prairie)
No, the feud isn’t between Laura and Nellie Olsen--they were besties off screen. Instead, there was discomfort between co-stars at the time: married couple Laura and Almanzo a.k.a. Melissa Gilbert and Dean Butler.
Melissa Gilbert, age 15 at the time, didn’t want to kiss a fully grown man with stubble, and the age difference between the two provided a huge stumbling block to the series. Writers eliminated most of the kissing/intimate scenes and replaced them with side hugs. Gilbert and Butler are friends today.
The Entire Cast (The Dukes of Hazzard)
While the Dukes seemed to be a family that couldn’t be any closer, in real life, the actors weren’t friendly at all with one another, and there was a lot of fighting on the set. Tom Wopat (Luke Duke) was a serious actor who was unhappy with his role and often complained about the stupid scripts.
John Schneider (Bo Duke) was happy to be included but often shrunk his pants so that his "package" was more prominent. Catherine Bach was very shy (yes, even in those shorts), and Denver Pyle only did his schtick and left. Even today, these actors go through serious negotiations before reunion appearances to garner "better billing" or a "more advantageous" position on a stage.
Eve Plumb & Maureen McCormick (The Brady Bunch)
As you might expect, this very Brady feud revolved around Marcia, Marcia, Marcia. Eve Plumb (Jan Brady) and Maureen McCormick (Marcia Brady) had a long-standing feud as child actors who simply didn’t like one another.
Rumors of a lesbian affair (they were children) is believed to be at the core of the issue, plus the stress of everyday shooting as young actors. The fallout was so great that several Brady Bunch reunions were canceled because of the girls. It was during the Brady Bunch house renovation that they straightened out their relationship.
John Belushi & The Writers (SNL)
John Belushi was a comedic genius to be sure. However, his need to sabotage the female writers and co-stars was due to the fact that he didn’t believe women could be funny.
Clearly, Lorne Michael knows a thing or two about funny women--as they have continued to be an integral part of the show both as writers and actors up through today.
Betty White & Bea Arthur (The Golden Girls)
Golden Girls is legendary for its characters' sass and witty comebacks, but apparently, not all of those underhanded insults were just acting. It's not entirely clear on why exactly Arthur disliked White.
However, White claimed it might have had something to do with her positive attitude. White said in a 2011 interview that Arthur wasn't a fan of White's cheerfulness, as Arthur herself had a very serious and professional attitude.
Roz Kelly & Henry Winkler (Happy Days)
Everyone knows how cool The Fonz was, and the cast was thrilled when the writers gave him a new, cool girlfriend. Enter Roz Kelly as Pinky Tuscadaro--slated to be his long-time lover.
However, Kelly found herself at odds with Winkler. After clashing with the rest of the cast and crew, poor Pinky was written out after only three episodes. Later on, Kelly claimed that she didn’t have anything in common with a bunch of rich kids as she grew up on welfare, which is not exactly a convincing argument.
Gabe Kaplan & Marcia Strassman (Welcome Back, Kotter)
As the title character, Gabe Kaplan was a lovable comedian. Despite his presence and other strong actors on the show, the wheels came off of Welcome Back, Kotter pretty quickly.
Marcia Strassman, who played his wife, was absolutely miserable doing scenes with Kaplan and hated the series. Things grew so heated on set that everyone was forced to take sides. During the fourth season, Kaplan himself was reduced to appearing in only a handful of episodes even though it was "his" show.
Farrah Faucett/Kate Jackson & ABC (Charlie's Angels)
With a hit show and a cast to dream about, ABC and Aaron Spelling felt like they hit the jackpot with Charlie’s Angels. However, at the end of the first season, Farrah resigned, and that caused a legal battle--as all three angels had signed five-year deals. ABC reluctantly released her from her contract, and a new angel was found in Cheryl Ladd.
However, trouble continued in the 3rd season--Kate Jackson was unhappy with her part and sought time off to shoot the movie Kramer vs Kramer. The producers refused her, and the part of Joanna Kramer went to Meryl Streep, who won as Oscar. Kate got her way and was dropped after causing several script incidents.
Nancy Kulp & Buddy Ebsen (The Beverly Hillbillies)
Jane and Jed had their share of problems on The Beverly Hillbillies, and the disconnect between the two stars didn’t stop when the cameras wrapped. Kulp and Ebsen were reported to have a very combative relationship on set, often arguing over politics and personal disagreements.
Ebsen, a lifelong conservative Republican commonly quarreled with the more liberal Kulp. Numerous cast members have commented on their tumultuous relationship on set, claiming that calm discussions would regularly escalate to yelling and name calling.
Larry Hagman & CBS (Dallas)
Let's go back to the summer of 1980 when J.R. had been shot and America was starting to go Dallas crazy. Larry Hagman suddenly became a huge star and realized it was the perfect time to renegotiate his contract. But CBS, Lorimar, and Phil Capice disagreed.
So, Larry went on strike. He literally left the show and left California--refusing to return to work unless he got a hefty salary raise. On June 12, 1980, the first day of shooting for the new season, Larry was conspicuously absent from the set. After ten long, hot days, Lorimar gave into Hagman’s demands and paid him a whopping $75,000 per episode.
Suzanne Somers & John Ritter (Three's Company)
Somers played beloved secretary Chrissy Snow for five seasons, but her contract was not renewed after she asked for a raise that would put her on par with co-star John Ritter's salary. "So, we went in to renegotiate for year six because we had to, my contract was up," she explains.
"And they fired me. They fired me for asking to be paid commensurate with the men.” But the actual feud arose after Somers was fired, mostly because Ritter was mad that that she considered herself on par with his humor. Somers claimed she was shunned by everyone on the cast and never spoke to anyone again. She and Ritter did make peace prior to his death.
Andy Griffith & Frances Bavier (The Andy Griffith Show)
Frances Bavier, beloved by millions as Aunt Bee, faced her lonely final days filled with bitterness because Andy Griffith had heartlessly turned his back on her. Stricken by terminal breast cancer, Frances spent her final days in Siler City, N.C.--the same state that was home to Sheriff Andy Taylor’s fictional hometown of Mayberry. The actress, who was in frail health, was only saddened when producers contacted her to play Aunt Bee in the 1986 reunion TV-movie Return to Mayberry.
Frances was so incensed that not even Ron Howard, who grew up playing Andy’s son, Opie, could change her mind. Ron had been one of the few cast members who cared enough to stay in touch with Frances in the years after the show ended, said one of Howard’s close pals. Frances then became more bitter when her character was killed off in the TV movie.
Jean Hagen and Danny Thomas (Make Room for Daddy)
During the first three seasons, Danny Thomas's character, Danny Williams, was married to Jean Hagen's character, Margaret. Yet not everything was perfect in classic sitcom land.
Thomas and Hagen reportedly clashed on the set and didn't care that much for one another. Hagen tired of the show and of Thomas, and she left at the end of the third season. Thomas was apparently so incensed at her leaving that he demanded the writers kill off the character.
George Peppard and Mr. T (The A-Team)
George Peppard considered himself a "proper movie actor" and took the role of the elder in The A-Team. However, it didn’t take long to see that Mr. T was going to be the star.
Things went from bad to worse when Peppard found out that Mr. T was being paid more than he was and refused to speak to him directly--sending messages through Benedict. Peppard refused to even use his name and called him "the man with the gold”. Robert Vaughn joined the cast in the fifth season because it was believed he could ease the tensions between the men.
Will Smith & Janet Hubert (The Fresh Prince of Bel-Air)
On-screen, it would be hard to notice that Will Smith and aunt Vivian actress, Janet Hubert, didn't get along. Conflicts over money and personality clashes led to Hubert's dismissal and Aunt Viv's recasting after season three aired.
Since then, Hubert has publicly criticized Smith and claimed that he and another actor destroyed her career. Even 25 years later, that feud has gone on strong. In 2016, during the Oscars, Hubert posted a dig at Smith while also slamming Jada Pickett Smith.
Bruce Willis & Cybill Shepherd (Moonlighting)
Constant fighting and endless screaming before and after every take led to the downfall of this popular TV series. Shepherd and Willis despised each other from the first day to the very last moments of filming for Moonlighting's fourth and final season.
Most of the drama came from a delay in shooting due to Shepherd taking a longer maternity leave while Willis was trying to launch his movie career. At the time, Willis was relatively unknown, and he felt Shepherd was getting in the way of his future.
Terri Hatcher & Marcia Cross (Desperate Housewives)
Desperate Housewives makes a reappearance, which is honestly unsurprising considering the drama both on-screen and off. Hatcher was always said to be the loner of the group, and for some reason, felt particularly distant to Cross.
The two got into an argument after both Cross and Eva Longoria threatened to leave a photo shoot for Vanity Fair's cover in 2005 if they put Hatcher in the center. This show was apparently full of feuds, but this was one of the ugliest.
Stana Katic & Nathan Fillion (Castle)
On-screen, these two seemed like the perfect, bickering will-they-or-won't-they couple that eventually married in the seventh season. But off-screen, things couldn't be more different. Supposedly, Katic and Fillion were sent to couples counseling as a way to try and resolve their issues.
Apparently, the two refused to speak to each other offset. Katic's decision to leave the show after season eight was rumored to be, at least in part, due to her rocky relationship with Fillion.
Penny Marshall & Cindy Williams (Laverne & Shirley)
With the creator of the show as her brother, it was unsurprising that Penny was cast as one of the leading roles. However, Marshall's co-star Cindy Williams claimed that Penny always wanted her gone so that she could have the spotlight all to herself.
Whether or not if that's how Marshall felt, that's how it ended. Williams got pregnant at the beginning of the eighth season, and the studio refused to give her the time off she needed, resulting in her filing a $20 million lawsuit to get her out of the contract.
Jennie Garth & Shannen Doherty (90210)
90210 is known for its drama both on-screen and off, though the on-screen drama was nowhere as fun to watch as what unfolded off-screen. Recently, Garth has said that the root of the problems simply stemmed from two similar young girls who were just trying to find their individual voices.
At the height of the feud, there was supposedly a physical fight between the two girls, after Doherty pulled up Garth's skirt and flashed the crew. The two have since reconciled and get along much better now as adults.
Alyson Hannigan & Sarah Michelle Gellar (Buffy)
Yes, it's true. The defenders of Sunnydale, the legendary witch and slayer duo, actually couldn't stand each other. Initially, the two had gotten along well in the early days of Buffy the Vampire Slayer, but as their careers advanced they began to butt heads more and more. Hostility flared into fights out of nowhere toward the beginning of the third season.
The whole feud came to a head when Gellar announced that season seven would be the last one. The only problem? The cast and crew hadn't been told. Hannigan was furious at how she and the rest of the cast were told and publicly ridiculed Gellar.
Charlie Sheen & Chuck Lorre (Two and a Half Men)
Charlie Sheen's behavior during the latter half of his time on Two-and-a-Half Men was nothing short of erratic and insane. Sheen very blatantly had a drug problem but vehemently refused to acknowledge it or accept any help from anyone.
This apparently included show co-creator, Chuck Lorre. Sheen repeatedly verbally attacked Lorre in unhinged interviews, and the feud between the two is still alive and well.
Isaiah Washington & T.R. Knight (Grey's Anatomy)
An off-screen argument-turned-fight between Patrick Dempsey and Isaiah Washington went horrendously awry and became one of the more infamous tussles from the show. After Washington's assault on Dempsey, he supposedly used homophobic slurs in reference to Knight (an openly gay actor).
The issue angered many in the LGBT community and was glossed over for a while after Washington released an apology for his behavior. At least, until he directly contradicted his apology by claiming he never even said the phrase. This controversy eventually led to Washington being fired a few months after the incident.
Shannen Doherty & Alyssa Milano (Charmed)
Doherty is the first of our repeat offenders on this list. After her time on 90210, Doherty switched to Charmed, where more co-star calamity plagued her. Milano chalked up their feud to major personality clashes coupled with the countless hours they spent with each other on-set.
Paramount, the studio behind Charmed, wound up having to hire a mediator to try and work out the girls' differences. Unfortunately, it didn't work. After a while, it became clear that one of the girls had to go, and the studio decided it would be Doherty.
America Ferrera & Lindsay Lohan (Ugly Betty)
Lohan started out as a guest appearance on ABC's sitcom Ugly Betty, and her run was easily the most tumultuous and troubled. Ferrera and Lohan reportedly never got along during filming, and they frequently butted heads.
Supposedly, Lohan's attitude was to blame, and it thwarted her and Ferrera's on and off-screen chemistry. Ironically, Lohan's character was the high school nemesis of Ferrera's. How appropriate.
George Takei & William Shatner (Star Trek)
Anyone who was a fan of the cult-favorite Star Trek obsessed over the camaraderie on the USS Enterprise, but surprise, surprise--not everyone was quite so buddy-buddy once the cameras stopped rolling. Most notably, Shatner and Takei spent a good portion of their time on Star Trek blatantly ignoring the other's existence as their bad blood escalated.
Takei repeatedly claimed that Shatner was self-centered and egotistical and never turned down the opportunity to publicly call out his former co-star. To be fair, Shatner equally served whatever Takei dished out. The two still sometimes take blows at each other in the media.
Kim Cattrall & Sarah Jessica Parker (Sex and the City)
Even though the two played best friends on the popular TV show, they reportedly completely ignored each other whenever they weren't filming together. Supposedly, the issues came down to Parker making more money than Cattrall and the rest of the cast.
Catrall was, obviously, less than thrilled. Once the show was over, and after the movie was completed, the two seemed to get along fine together. The feud was recently rekindled when Cattrall publicly bashed the film and claimed she would never reprise her role from the series.
Chevy Chase & Dan Harmon (Community)
Oh, the irony. In a show called Community, there was absolutely no sense of community to be found amongst the actors once the cameras stopped filming. Show creator Dan Harmon and actor Chevy Chase often fought over the direction of the show and Chase's character, Pierce Hawthorne.
These fights resulted in Chase walking off the set more than once and raised tensions amongst the cast and crew. By the end of season three, Harmon was fired which was paramount to ending the series altogether. The fourth season was widely considered a disaster without Harmon, and by season five, Harmon was back, but Chase left before season four ended.
Jason Alexander & Heidi Swedberg (Seinfeld)
Seinfeld was a show that loved having characters that were both engaging and interesting but also annoying to the point you thought about turning the show-off. Susan, George's on-again-off-again girlfriend, played by Swedberg, was one of these characters.
Fans were surprised by Swedberg's sudden departure in season seven, but Alexander later revealed it was because Swedberg was almost impossible to work with. Alexander hated doing scenes with due to her work habits and asked that she be written off the show.
Nicollette Sheridan & Marc Cherry (Desperate Housewives)
Desperate Housewives had its share fair of drama, but one ended in one of the stars filing a $20 million lawsuit. Nicollette Sheridan accused show creator Marc Cherry of assault on set, claiming that she had been hit on the head.
After she had tried to report Cherry's behavior, she was written out of the show. Ultimately, the judge declared a mistrial after the jury deadlocked, and subsequent lawsuits were tossed out.
Mila Kunis & Ashton Kutcher (That 70s Show)
This one, no doubt, comes as a shock to several of you, but it's the truth! Though now happily married, Kunis and Kutcher originally couldn't stand working together and would avoid each other on-set when they first worked together on That '70s Show.
Some people chalked it up to their six-year age gap as Kunis was 15 when they'd first met, while Kutcher was 21. Everything obviously worked out in the end as the two have been married since 2015. They also have two adorable children.
Vivian Vance & William Frawley (I Love Lucy)
While Lucy and her husband Desi Arnaz played the iconic happy couple, Lucy and Ricky, their friends in the show Ethel and Fred Mertz (Vivian Vance and William Frawley, respectively) had trouble in paradise. The two actors were not on good terms from the very beginning.
Vance immediately complained to Ball that Frawley was much too old to pay her husband with their 22-year age gap. Frawley overheard this complaint, and it only spiraled from there. The hatred never went away and only grew with every episode.
Charlie Sheen & Selma Blair (Anger Management)
Sheen makes our third repeat offender on this list, and he's definitely no stranger to controversy. Blair and Sheen played rival therapists turned lovers in the series until Blair was very suddenly dropped from the cast in the early part of the second season.
The sudden drop of Blair led many to believe it was Sheen's doing. Supposedly, Blair learned she was being fired from an angry text message from Sheen himself. Sheen obviously denied this.
John Forsythe & Joan Collins (Dynasty)
There was plenty of drama on-screen between Forsythe and Collins's characters Blake and Alexis, and it seems that drama followed them into their lives off-screen. Collins said that Forsythe never truly warmed up to her and kept her at arm's length during their time together.
Supposedly, Forsythe even went an entire season of the show without speaking to Collins outside of when they filmed together. That obviously didn't work well, and the show certainly suffered.
Chad Michael Murray & Sophia Bush (One Tree Hill)
Talk about awkward. Murray and Bush originally fell in love on the set of the show One Tree Hill, and they married after only a few months of dating. Though that happiness they found was short-lived, and they divorced within five months of their marriage.
They then continued to work together (at times, playing a couple) until Murray left the show in 2009. The animosity brought on by their marriage and subsequent divorce made things awkward on set, and the two actors couldn't stand each other.
Kirk Cameron & Julie McCulloch (Growing Pains)
A devout Christian actor and an ex-Playboy-model-turned-actress walk onto a set to play on-screen sweethearts. Sounds like the set up to a joke, but instead of a laugh, you get a lot of problems. Cameron played ladies man Mike Seaver in the show, opposite McCulloch's character Julie.
One thing leads to another (as it always does), and the two characters were looking at marriage in the show. Cameron wasn't happy with that. Cameron took issue with McCulloch's previous posing with Playboy and demanded that she be written out of the show. This action alienated Cameron from both McCulloch and other cast and crew members.
William Shatner & Leonard Nimoy (Star Trek)
Yes, I know, this one's surprising. Shatner makes his reappearance late on this list, this time facing down on-screen best friend Leonard Nimoy, the actor who played Spock. Similarly to his story with Takei, Shatner wanted to be the ultimate star of the show, and Nimoy was in his way.
Shatner was known for stealing lines and being nothing short of controlling on set. Though, unlike with Takei, Nimoy and Shatner eventually reconnected in the wake of personal tragedies. Due to disagreements about a documentary Shatner was making, the two hadn't spoken in the five years leading up to Nimoy's death in 2015.
Julianna Marguiles & Archie Panjabi (The Good Wife)
You know things are really bad when co-stars won't even shoot their final scene together. Margulies and Panjabi did just that, having to be superimposed together in post-production because the two couldn't stand to even be in the same room as each other.
The animosity between the actresses took a close TV friendship that was adored by fans and destroyed it, and no one really knows why. What we do know is that they didn't appear in episodes together (or at least not very often) following the release of the feud.
