#1. Kenny Baker and Anthony Daniels, Star Wars
Although they played (robot) friends R2-D2 and C-3PO onscreen, Baker and Daniels couldn’t have been less so. The feud apparently started when Baker attempted to say hello to Daniels one morning early in filming, and Daniels turned his back on him, stating “Can’t you see I’m having a conversation?” This struck a chord with Baker: “It was the rudest thing anyone had ever done to me. I was furious. It was unbelievable.” This early scuffle set the tone for the rest of their filming relationship, Baker later saying in 2006: “We were both in our droids; there was no interconnection at all. We couldn’t hear or see each other.” And it seems they were both fine with that.

#2. Julia Roberts and Nick Nolte, I Love Trouble

Trouble was truly the choice word when these two played onscreen lovers in the 1994 rom-com I Love Trouble. Rumours of the tension began flying even before the film came out, claiming that Roberts found Nolte to have a machismo attitude, after which Nolte was driven to agitate Roberts even more. Apparently their dislike for each other became so intense, the two ended up having more scenes with their stand-ins than with each other.

#3. Patrick Swayze and Jennifer Grey, Dirty Dancing

Dirty Dancing still stands as one of the most romantic film of the ’80s (and of all time), but offscreen things weren’t as peachy. In Swayze’s autobiography, The Time of My Life, he reveals how he didn’t get along with his character’s romantic interest on set. Apparently, Grey was “highly emotional” and prone to “silly moods,” which he found to be unprofessional, and caused a subsequent rift between the two costars.

#4. Will Smith and Janet Hubert, The Fresh Prince of Bel Air

While The Fresh Prince of Bel Air seamlessly tried to replace Aunt Viv midway through the show, viewers wouldn’t let it go unnoticed. According to Hubert, her dismissal was all Smith’s doing in 1993 when she was fired and replaced by Daphne Reid. Hubert later called Smith an “egomaniac,” and stated that he is the only reason she would never do a Fresh Prince of Bel Air reunion.

#5. Claire Danes and Leonardo DiCaprio, Romeo and Juliet

In Baz Luhrmann’s 1996 film adaptation of Romeo and Juliet, Danes and DiCaprio played the two of the most iconic lovers in history. But, offscreen things could not have been less romantic. According to the reports, Danes found DiCaprio “irritatingly immature,” as he became known for playing pranks on the cast and crew members. On the other hand, DiCaprio found Danes “annoyingly reserved and uptight.” In real life, these two “star-crossed lovers” were just a set of cross stars.

#6. Bill Murray and Lucy Liu, Charlie’s Angels

Bill Murray has long been known as one of the most lovable, comedic legends – it only makes sense that he would get along with any and every co-star. Not true when it came to Lucy Liu. Apparently the two got in a scuffle while rehearsing a scene, in which Murray insulted Liu and the delivery of her lines. Murray would later forego appearing in the Charlie’s Angels sequel.

#7. Rachel McAdams and Ryan Gosling, The Notebook

While the two made one of the most romantic onscreen couples of all time, things apparently had a rocky start, and reports state that Gosling frequently complained about McAdams. In an interview with writer and director Nicholas Sparks, he stated: “Maybe I’m not supposed to tell this story but they were really not getting along one day on set. Really not. And Ryan came to me, and there’s 150 people standing in this big scene, and he says, ‘Nick come here.’ And he’s doing a scene with Rachel and he says, ‘Would you take her out of here and bring in another actress to read off camera with me?’ I said, ‘What?’ He says, ‘I can’t. I can’t do it with her. I’m just not getting anything from this.’ After an impromptu therapy session, the two actors were able to work things out, so much so that they even dated offscreen once filming wrapped from 2005 to 2007.

#8. Lea Michele and Naya Rivera, Glee

With the two striking brunettes allegedly finding it hard to get along since filming started in 2009, things escalated even more in 2014 when the actresses had “a major altercation” on set. Michele apparently wanted Rivera off the show and soon after Rivera was written out in the final two episodes of season five and didn’t return for the sixth and final season of Glee.

#9. Harrison Ford and Josh Hartnett, Hollywood Homicide

With a legend like Harrison and dreamboat like Josh Hartnett coming together in an action-filled drama, you would hope the two would become best buds, but that wasn’t the case in Hollywood Homicide. Ford and Hartnett apparently fought through the entirety of filming, Ford calling Hartnett a “punk”, while Hartnett struck back and called Ford an “old fart.” Hartnett later admitted that the two would barely make eye contact with each other on set.

#10. Debra Winfer and Shirley MacLaine, Terms of Endearment

Terms of Endearment swept the 1984 Academy Awards, and the tension between the two star actresses offscreen was award-worthy as well. With both actresses having reputations of being “difficult,” things were bound to start off on the wrong foot. They reportedly hated each other so much that they got into physical altercations; and when both were nominated for the Best Actress Oscar, it only added fuel to the fire. MacLaine would go on to win, and famously shouted “I deserve this!” when her name was called over Winger’s that night.
