Hollywood has always been a land of glitz, glamour—and grudges. Some of the greatest on-screen rivalries didn’t just stay on the silver screen; they spilled over into real life, creating legendary feuds that captured the attention of fans and fueled tabloid stories for decades. Let’s take a look at some of the most famous on-screen enemies who continued their battles when the cameras stopped rolling!

Tony Curtis vs. Marilyn Monroe: Not-So-Sweet Like Sugar

Tony Curtis and Marilyn Monroe starred together in “Some Like It Hot,” but their chemistry off-screen was anything but sweet. Curtis once infamously compared kissing Monroe to "kissing Hitler." Though he later claimed the comment was a joke, it was clear that there was plenty of tension on set.

Monroe was known for her tardiness and her struggles with lines, which tested Curtis's patience. Despite their on-screen romance, the atmosphere off-camera was frosty, filled with frustration rather than flirtation.

Bette Davis vs. Joan Crawford: The Ultimate Feud

The on-screen rivalry between Bette Davis and Joan Crawford in “What Ever Happened to Baby Jane?” is legendary, but the real drama started long before the cameras started rolling. Their feud is one of the most infamous in Hollywood history—filled with jealousy, competition, and some truly biting remarks.

Their animosity began back in the 1930s, when Joan Crawford was Hollywood royalty and Bette Davis was an up-and-coming actress hungry for serious roles. Things escalated when Crawford allegedly stole Davis’s love interest, Franchot Tone, by marrying him. Davis never forgave her, and when they were cast together in What Ever Happened to Baby Jane?, the tension between them exploded.

On set, Crawford wore weights to make herself heavier when Davis had to carry her, while Davis reportedly “accidentally” kicked Crawford in the head during a scene. The off-screen rivalry only added to the film’s intensity, making their performances unforgettable. Their feud was so well-known it even inspired the TV series “Feud: Bette and Joan” decades later.

William Shatner vs. George Takei: The Starship Spat

The rivalry between William Shatner and George Takei, stars of the original “Star Trek” series, has lasted for decades and has become almost as famous as the show itself. Shatner, who played the dashing Captain Kirk, and Takei, who portrayed the heroic Sulu, were on-screen allies. But off-screen, there was no love lost between them.

Takei has often spoken about Shatner’s larger-than-life ego, claiming that Shatner tried to steal the spotlight and treated his co-stars dismissively. Shatner, on the other hand, has accused Takei of using his name for publicity. Their feud re-ignites from time to time, often through interviews and public comments, proving that even in the vastness of space, grudges can endure.

Sylvester Stallone vs. Richard Gere: From Movie Set to Lifetime Feud

The feud between Sylvester Stallone and Richard Gere started on the set of the 1974 movie “The Lords of Flatbush”—and it all began with a chicken sandwich. According to Stallone, tensions were already high between the two actors when Gere accidentally spilled mustard on Stallone during lunch. Things got heated, and Gere was eventually kicked off the set, with the role recast.

Since then, the two have kept their distance, and neither misses an opportunity to subtly throw shade at the other. Stallone has joked that Gere still blames him for being kicked off the movie, making their feud a long-lasting bit of Hollywood history.

Ryan Gosling vs. Rachel McAdams: The Notebook Sparks Fly

Ryan Gosling and Rachel McAdams created romantic magic on-screen in “The Notebook,” but during filming, the reality was far less dreamy. Gosling and McAdams reportedly clashed so much that Gosling asked the director if they could bring in another actress to read lines with him because he couldn’t stand working with McAdams.

Despite their on-set tensions, something must have shifted after the film wrapped, because they famously ended up dating in real life for several years. Their off-screen relationship became almost as iconic as their on-screen love story, turning a heated rivalry into a real-life romance—at least for a while.

Nick Nolte vs. Julia Roberts: No “Love” Lost

Nick Nolte and Julia Roberts co-starred in “I Love Trouble,” but the only trouble was that they couldn’t stand each other. Roberts reportedly found Nolte’s on-set behavior exasperating, and Nolte found her attitude equally difficult. The tension was so thick that they often filmed their scenes separately, with body doubles stepping in to create the illusion of on-screen chemistry.

After filming, Roberts didn’t hold back in interviews, calling Nolte "disgusting," while Nolte said she was “not a nice person.” Their off-screen animosity was far more entertaining than the romantic comedy they were supposed to be starring in!

Vin Diesel vs. Dwayne “The Rock” Johnson: The Fast and Furious Fallout

Vin Diesel and Dwayne "The Rock" Johnson might have played family on screen in the “Fast & Furious” franchise, but behind the scenes, things got pretty tense. Their feud started during the filming of “The Fate of the Furious”, with Johnson posting a cryptic social media message about some of his co-stars being "candy asses" and unprofessional.

It became clear that the target of his frustration was Vin Diesel. The feud reportedly centered around creative differences and issues over the film's direction. The tension got so bad that the two actors didn’t film any scenes together in the eighth installment of the series, and Johnson eventually left the main franchise to star in “Hobbs & Shaw” instead. Despite a few attempts at reconciliation, their rivalry remains one of the most well-known in modern Hollywood.

Shannen Doherty vs. Alyssa Milano: Witchy Tensions on “Charmed”

The hit TV show “Charmed” had a lot of magic on-screen, but off-screen, the sparks were less enchanting. Shannen Doherty and Alyssa Milano famously clashed on set, which led to ongoing tensions. Doherty, known for her fiery temperament, reportedly had difficulty getting along with Milano, and the stress between the two eventually became too much for the show to handle.

In 2001, Doherty left the show after the third season, leading to plenty of speculation about whether her off-screen drama with Milano was the real reason behind her departure. Milano has since said that the atmosphere on set improved significantly after Doherty left, proving that even witches can't always make the magic work.

Bill Murray vs. Lucy Liu: Charlie's Feuding Angels

Bill Murray and Lucy Liu worked together on “Charlie’s Angels”, but their chemistry was far from angelic. During filming, tensions flared when Murray allegedly criticized Liu’s acting ability, leading to a heated argument that almost turned physical. Reports claim that Liu stood up for herself, resulting in the two actors having a major falling out on set.

The feud was so intense that Murray did not return for the sequel, “Charlie’s Angels: Full Throttle”—his role was replaced by Bernie Mac. Though Murray has downplayed the incident in interviews, the feud remains one of Hollywood’s more dramatic behind-the-scenes stories.

Debra Winger vs. Shirley MacLaine: Terms of Un-Endearment

On the set of “Terms of Endearment”, Debra Winger and Shirley MacLaine portrayed a complicated mother-daughter relationship, and their off-screen dynamic was just as intense. The two actresses had wildly different personalities—Winger was known for her unpredictable and eccentric behavior, while MacLaine was more seasoned and disciplined.

Their clashes led to on-set tension, with stories of Winger deliberately antagonizing MacLaine, including allegedly lifting her skirt in one incident. Despite the turmoil, both actresses delivered powerhouse performances, earning them Academy Award nominations—MacLaine eventually won the Oscar, which couldn’t have helped their already strained relationship.

Leonardo DiCaprio vs. Claire Danes: Romeo & Juliet's Off-Screen Drama

In Baz Luhrmann’s “Romeo + Juliet”, Leonardo DiCaprio and Claire Danes created one of the most iconic romantic duos of the '90s. However, their chemistry was reportedly much cooler off-screen. Danes found DiCaprio's constant pranks and goofing off annoying, while DiCaprio thought she was too uptight.

Though they kept it professional during filming, their differing personalities made for an uneasy on-set atmosphere. Despite the off-screen tension, the movie became a cult classic, and their portrayals of star-crossed lovers are still beloved today.

Charlize Theron vs. Tom Hardy: Mad Max Meltdown

On the set of “Mad Max: Fury Road”, Charlize Theron and Tom Hardy had a famously tense relationship. Filming conditions were grueling, with long days in the desert, and the pressure took a toll on their off-screen dynamic. Theron reportedly found Hardy’s intense method-acting approach difficult to work with, while Hardy struggled with Theron's demands for professionalism.

In a later interview, Theron admitted that the tension came from the challenging nature of the shoot, and Hardy acknowledged that he might have been too intense. In a case of art imitating life, their on-screen antagonism translated well to their roles as Furiosa and Max, adding an extra edge to their performances.

Chevy Chase vs. the Cast of “Community”: No Laughing Matter

Chevy Chase had a well-documented feud with the cast and crew of “Community”, particularly with the show’s creator, Dan Harmon. Chase’s behavior on set was described as difficult and erratic, and he reportedly clashed with co-stars like Donald Glover. Harmon even played voicemails left by Chase in which he criticized the show during a public event, further escalating tensions.

The feud came to a head when Chase left the show before its fourth season, leaving behind a legacy of comedic brilliance mixed with behind-the-scenes drama. It’s a reminder that even in comedy, sometimes there’s no room for jokes.

Isaiah Washington vs. Patrick Dempsey: Grey's Anatomy Drama

The set of “Grey’s Anatomy” wasn’t immune to off-screen drama either. Isaiah Washington and Patrick Dempsey had an infamous on-set altercation that became a major scandal. Washington reportedly used a homophobic slur during a confrontation with Dempsey, which led to severe backlash.

The incident not only affected their relationship but also the entire dynamic of the cast. Eventually, Washington was fired from the show, and the feud became one of the most publicized controversies in television history.

Hollywood has always thrived on drama, and these feuds show that sometimes the most intense rivalries aren't scripted—they’re real. Whether it’s classic stars like Bette Davis and Joan Crawford or more modern battles like Shatner and Takei, these legendary on-screen rivalries turned off-screen grudges are proof that even Hollywood’s brightest stars aren’t immune to a little bit of drama... or a lot of it!
