12 Craziest On-Set Celebrity Feuds of All Time

Discourse has been with us since the beginning of time. It’s in human nature to disagree, but it’s how we handle conflict that defines us. Hollywood has had its fair share of celebrity feuds, ranging from mild to wild. Strong personalities in the TV and film world are prone to disagreements, which stem from personal feelings, power struggles, or specific incidents or behaviors. From physical fights to verbal assaults, we’ve rounded up some of the craziest on-set celebrity feuds of all time. You won’t believe which of these co-stars hate each other!

Rebel Wilson’s new memoir, “Rebel Rising,” reveals disturbing allegations against Sacha Baron Cohen during the filming of the action-comedy “The Brothers Grimsby” in 2016. Wilson asserts that working with Cohen was “the worst professional experience” she’s ever endured.

Cohen is accused of being a “massive a**hole” for allegedly bullying, harassing, humiliating, and gaslighting Wilson during their time co-starring as on-screen husband and wife. Not only does Wilson claim Cohen pressured her to appear nude, but he allegedly asked her to “stick your finger up my butt” while filming the final scene of the movie.

In addition to the allegations of sexual harassment, Wilson claims that Cohen posed a plan to her for them to publicly engage in a kiss to help promote the film with a good old-fashioned scandal. This assertion was denied by an insider who worked on the production. Wilson also alleges that Cohen harassed her ahead of her memoir’s release to block its publication. In fact, at the time of this writing, the book's release is still delayed in the U.K. and Australia.

Cohen, of course, vehemently denies all allegations and purports the finger-in-the-rear situation was documented on video with Wilson appearing to be on board. Is it a coincidence that Cohen’s divorce from Isla Fisher was announced on April 5, mere days after the book’s U.S. release? Seems a little sus to me.

Don’t expect to see this duo on screen together anytime soon; Wilson said she will never work with Cohen again.

I’ve always been a sucker for teen dramas on television, but this well-known feud between actresses has extended off the screen for decades. “Beverly Hills, 90210” is known for its drama and tackling controversial storylines that still stand up 30 years later. What also still stands? The feud between Shannen Doherty and Jennie Garth.

While the actresses played on-again-off-again friends in the series, there was definitely no friendship behind the scenes at all. Doherty shared her experience working on the show on a recent episode of her new podcast, “Let’s Be Clear.” Allegedly, Doherty attempted to prank Garth which led to an altercation between them requiring their male co-stars to physically separate them. Brian Austin Green shared on the podcast, “I remember it got really rough and competitive for you all,” he agreed. “That was not an easy situation to watch.”

Speaking of podcasts, Garth recently announced she will be hosting her own, “I Choose Me.” I’m interested to see if she also dives into the feud. While promoting the “BH90210” reboot in 2019, Garth shared with Andy Cohen that the pair of actresses “took it outside.” She confirms that the guys held them back so no physical contact was made. Co-star Tori Spelling has said she did her best to avoid it and stayed in her dressing room when it was happening.

The rumor mill has run strong over the years in regards to the tension between the ‘90s stars. Interestingly, Doherty and Garth are both participating in various convention panels together. I’d love to be a fly on the wall to catch any personal interactions between them!

The legendary rivalry between dueling divas Joan Crawford and Bette Davis is one for the ages. The iconic actresses competed for the same roles and were alleged to constantly attempt upstaging each other, plus took shots at one another in the media. One notable jab from Davis, “[Crawford] slept with every male star at MGM — except Lassie.” Yikes.

The feud is so intense that it inspired an entire season of Ryan Murphy’s anthology television series, “Feud: Bette & Joan.” The show centered on the competitive and bitter conflict between the two while filming the 1962 Academy Award-nominated horror film, “What Ever Happened to Baby Jane.”

By the time the pair co-starred in their first and only film together, they were in their mid-50s. The feud was already long-standing by then, having been triggered in 1933 when Crawford’s divorce overshadowed Davis’ starring role in “Ex-Lady” and then intensified with other incidents. Crawford allegedly mocked the dress Davis wore to the 1936 Academy Awards, prompting her to apologize with flowers. Davis later returned them.

Numerous alleged altercations occurred on set. Crawford was on Pepsi’s board, so Davis installed a Coke machine in her dressing room. Crawford claims Davis kicked her in the head during a scene in which her character was intended to be hurt. Rumors swirled that stitches were required yet Davis maintained she “barely touched her.”

While filming “Any Given Sunday” in 1999, Jamie Foxx and LL Cool J came to literal blows while filming a scene at Miami’s Pro Player Stadium. Reports indicate that Foxx busted Cool J’s lip, prompting Cool J to knock Foxx out. The scene made the film, but the incident prompted the involvement of the Miami-Dade County Police.

Co-star Bill Bellamy has recently shared details about the altercation, stating that after years of feuding, they’ve since resolved their differences and laugh about it now.

The aptly-named series “Anger Management” could not be more on-brand for the clash of personalities between co-stars Selma Blair and Charlie Sheen. Blair allegedly voiced her concerns regarding Sheen’s work ethic and behavior. It’s alleged that Sheen (a series executive producer) refused to continue working with Blair and threatened to quit unless she was let go. Sheen reportedly used the C-word expletive in a text message to Blair firing her from the show.

It’s rumored that Blair considered a lawsuit but didn’t have the backing since the show had already planned to write off her character. Sheen firing Blair is the ultimate irony, given he was fired from “Two and a Half Men” for his behavior issues. Patterns are often telling of a person’s character, and Sheen has proven his behavior could use some improvement.

The 2000 film “Charlie’s Angels” is filled with bada** actresses, including Drew Barrymore, Cameron Diaz, and Lucy Liu. It was also known for bad on-set behavior on the part of Bill Murray. Murray allegedly spewed “unacceptable and inexcusable” language towards Liu during a rehearsal day. It was reported that Murray was not initially supposed to be at the rehearsal that day due to a family commitment but showed up to the set in a bad mood. The mood allegedly led to a heated assault of insults hurled at Liu who defended herself to Murray and still stands by her firm stance for not tolerating being berated.

The Liu incident isn’t Murray’s first feud rodeo. Murray also ran into trouble on the set of 2022’s “Being Mortal,” leading to production shutting down. Years earlier, Murray was involved with an on-set incident at “Saturday Night Live.” Jim Belushi allegedly pulled Murray and co-star Chevy Chase apart during a backstage brawl.

“Executive Decision” is a 1996 action-thriller film starring Steven Seagal and John Leguizamo. It seems the former felt he was the true executive on set. When Seagal allegedly announced to the movie cast and crew at a rehearsal, “I’m in command. What I say is law,” Leguizamo laughed. Apparently, that was not the correct reaction. Seagal allegedly threw an aikido elbow, knocking Leguizamo into a brick wall.

The feud is still going strong today, with Leguizamo quipping in interviews that he based his washed-up actor character in “The Menu” on Seagal.

Fans of the long-running medical drama “Grey’s Anatomy” are all too familiar with the 2007 feud between Isaiah Washington and Patrick Dempsey. In 2007, Washington was written off of the series in Season 3 following his firing from the show. Details of the fight are outlined in Lynette Rice’s book, “How to Save a Life: The Inside Story of Grey’s Anatomy.”

Apparently, there was a misunderstanding over each of the actors being on time on separate occasions, resulting in a physical altercation between Dempsey and Washington. Washington allegedly started a fight with Dempsey, pinning him against a wall. The incident ended with Washington using a derogatory, homophobic slur toward another cast member, T.R. Knight.

The feud between Sylvester Stallone and Richard Gere started in 1974 on the set of “The Lords of Flatbush” and still runs strong to this day. Stallone wasn’t a fan of Gere’s vibe from the start. The initial dislike turned into hatred over a greasy food blob dripping onto Stallone’s pants from Gere’s lunch in the backseat of a car during a break from filming on Coney Island. The former warned Gere ahead of time it would drip and then proceeded to throw him out of the car when it happened.

Gere was fired from the film. The two later had a run-in and near altercation at a party over Princess Diana. Allegedly, the fight was avoided after David Furnish broke it up. Like other actors known for their feuds, there’s more than one incident here, too. While filming “Tulsa King,” Stallone’s disparaging comments about background actors and their appearance led to the casting director quitting due to the toxic environment.

The feud between Sean Young and James Woods allegedly began when the two had an affair during the filming of the 1988 film, “The Boost.” The pair played a cocaine-addicted married couple on the screen, but apparently, Young felt spurned after the affair ended off-screen.

Woods filed a stalking and harassment suit against Young, alleging she terrorized him and his fiancee at the time. Allegations included Young leaving an iodine-soaked headless doll on their doorstep, and rumors swirled that she super glued Woods’ pen*s to his leg while sleeping. Excuse me, what? The suit was settled out of court with Young victorious; she won $227,000 to cover her legal bills.

Both have denied the affair and Young continues to deny the harassment she was accused of by Woods. Young has been seen as a controversial figure in Hollywood ever since.

Before the alleged triggering incident, Shia LeBeouf stated he and Tom Hardy would mess around, wrestling for fun during filming of the 2012 film “Lawless.” However, it was reported that Hardy interrupted an intimate moment between LeBeouf and his girlfriend at the time. Hardy allegedly threw his naked co-star over his shoulder and the two began wrestling in an actual fight. Allegedly, Hardy “accidentally” fell down a flight of stairs but told people on set that LeBeouf knocked him out.

In 2016, director John Hillcoat stated the actors were in fact in a fight and were physically restrained before coming to blows. Then, in 2019, LeBeouf spoke of the incident as a hilarious story and baseless rumor; he never knocked Hardy out and it was all in good fun. Hardy maintains he was knocked out cold by LeBeouf.

The 2022 psychological thriller “Don’t Worry Darling” left a couple of co-stars with, well, worries. The film was no stranger to controversy, which began when Harry Styles replaced Shia LeBouf after filming had already begun. The drama continued to transpire between co-stars Olivia Wilde (who was also the film’s director) and Florence Pugh.

The pair of actresses were said to engage in a screaming match on set. Allegedly, Pugh was upset over Wilde’s continued absences during filming, which may or may not have been due to her romantic involvement with Styles.

Pugh skipped out on many PR engagements promoting the film and has remained quiet about the alleged conflict. Alternatively, Wilde has maintained there are many untruths out there regarding the alleged feud between her and Pugh and has even praised the latter in interviews.
