Fans become invested in their favorite characters’ relationships. In fact, many become so invested in the onscreen chemistry that hey start shipping the real world actors too. Who hadn’t wished for a Cole Sprouse and Lili Reinhart union before the Riverdale co-stars were finally (sort of) confirmed to be a couple at this past San Diego Comic Con?
However, we don’t always get a romantic love story like Sprouse and Reinhart, but sometimes just learning that our fave actors eat pizza and play video games is enough to keep us going.
For every real-life Bughead, there’s an equally real Archie/Reggie nemesis situation going on. Many actors, despite their charisma and chemistry, find themselves hating their co-stars with a fiery passion.
Sometimes emotions run high during difficult filming procedures and sometimes the actors simply have nothing in common and can’t stand to be around their castmate.
Some actors attempt to put their differences aside and bury the hatchet years after production wraps, while others hold onto their grudge for dear life. Some attempted to downplay their passionate hatred for their coworker, but others have shouted their feelings of disgust from the rooftops for all the world to hear.
Here are the 8 Castmates Who Hated Each Other (And 8 Who Were Best Friends).
16 Friends: Joe Keery And Gaten Matarazzo
Stranger Things’ season 2 brought out the softer side of former bad boy Steve Harrington. He became an instant heartthrob and fans the world over wished that they had a Steve to their Dustin.
Adorably, Joe Keery and Gaten Matarazzo’s real-life relationship is just as loving and emotional as their onscreen counterparts’.
Keery and Matarazzo hang out offset, they constantly compliment each other, and Keery couldn’t help but become emotional when they performed a friendship test and had to tell each other how they felt about the other.
Keery has said on more than one occasion that his newfound friendship is his absolute favorite thing to come out of season 2. He carries so much love and respect for Matarazzo as an actor and person.
15 Hate: Leighton Meester and Blake Lively
Leighton Meester and Blake Lively were friends at one point, but eventually, the former Gossip Girls lost touch, resulting in the destruction of their beautiful friendship.
The two attempted to remain friendly after the series ended, but they eventually grew apart so much that Meester didn’t even bother to congratulate Lively on her marriage to Ryan Reynolds.
Despite former co-star Michelle Trachtenberg's insistence this past August that the actresses never really squabbled on set, Meester and Lively were seen to make a concentrated effort not to run into each other at Golden Globes party last January.
Both women attended the same party, husbands in tow. They could have easily taken some time out to catch up, but reports said the former castmates completely ignored each other’s existence.
14 Friends: Andrew Lincoln And Norman Reedus
Despite the sadness, fear, and trauma, at least one good thing came out of the zombie apocalypse. The end of the world brought Sheriff Rick Grimes and rough-and-tumble archer Daryl Dixon together.
They’ve repeatedly made it clear that they are more than friends and see each other as true brothers. Their real-life counterparts, Andrew Lincoln and Norman Reedus, feel very much the same way.
These best buds do nothing but compliment each other. Lincoln even thinks Reedus is the most brilliant actor he’s ever met. Reedus brags about Lincoln’s spot-on Southern accent.
While the sweetness is adorable, it’s nothing compared to the pair’s hilarious prank wars. Reedus likes to charge hotel purchases to Lincoln’s tab and the two have been unleashing glitter pranks on each other for years now.
13 Hate: Alyssa Milano And Shannen Doherty
It may be hard to imagine now, given the powerfully inspirational warriors that these two women have become, but there was once a time when they were relentless catty toward each other.
In recent years, Milano has shown support for Doherty’s struggle with breast cancer and the two have recently begun to connect frequently over Twitter.
This newfound friendship has been waiting in the wings for decades. Milano has previously been very forward about her and Doherty’s constant bickering and cold shoulders on the set of Charmed.
She revealed that the two would either be at each others' throats or that they would simply take turns refusing to acknowledge each other’s existence. Their feud is widely accepted as the reason for Doherty’s departure from the series.
12 Friends: Selena Gomez And David Henrie
Despite the Disney Channel’s Wizards Of Waverly Place being off of the air for five years now, Selena Gomez and David Henrie have remained close ever since.
When Henrie married Maria Cahill earlier this year, Gomez and the entire Wizards cast showed up for a mini-reunion. However, because they are totally brother and sister forever, Henrie told Gomez about his special day before he told anyone else.
Gomez happily shared photos of the event and wrote an adorable shout-out to her “big brother.” In her post, Gomez shared her intense feelings over the event but she also let fans know that Henrie’s wedding came as a surprise to nobody.
They all thought he was such a sweetheart they just knew he would get married first.
11 Hate: Jeri Ryan And Kate Mulgrew
For years fans have wondered if there was bad blood on the set of Star Trek: Voyager. Finally, 15 years after the sci-fi series left the air, Jeri Ryan revealed the truth: she and Kate Mulgrew hated each other.
Ryan admitted that the discord was largely due to her arrival on set. The media quickly latched onto her character, Seven of Nine, disrupting the established vibe of the already three-year-old show. Ryan said that the show’s captain was generally the most famous character, but hers became an immediate success, which left some of her castmates a little salty.
It’s alleged that Mulgrew led the charge, phoning in her scenes with Ryan and generally making the experience an unpleasant one. Ryan revealed the moment things started looking up for her on set was when she began dating the showrunner. Fancy that.
10 Friends: Mindy Kaling And BJ Novak
Mindy Kaling and BJ Novak played the on-again-off-again, head-over-heels in love (but also super annoyed by each other) Kelly Kapoor and Ryan Howard on The Office. Fans loved their hectic relationship and it turns out that that chaos was truer to life than you might think. Kaling and Novak’s real-life relationship was very much the same.
To this day, the pair frequently profess their love for each other as loudly and sappily as possible. They openly plan their possible future wedding, they publicly tell each other hot they look, and they never, never stop celebrating each other’s career achievements.
According to Novak, the only reason these two haven’t already tied the knot is because of the intensity of their early relationship… that, and the total embarrassment in store when friends and fans alike simultaneously yell, “I told you so.”
9 Hate: Channing Tatum And Alex Pettyfer
Magic Mike certainly seemed to be all good times and dancing, but Alex Pettyfer has always been very open about the bad blood between himself and co-star Channing Tatum on the set of the 2012 dance flick.
Pettyfer revealed that he and Tatum would frequently clash because his co-star simply didn’t like him… but he doesn’t blame Tatum for his disdain whatsoever. Sadly, Pettyfer said that his own insecurities, caused by constant criticism from his agents, prompted him to shut down and fail to socialize on set.
His quiet and removed attitude led the cast and crew to think that Pettyfer believed he was better than them, which really couldn’t have been further from the truth.
To add insult to injury, Pettyfer said he had moved out of an apartment owned by one of Tatum’s friends but had forgotten to pay his last month’s rent due to the untimely death of his cousin.
Once again, Tatum had been upset over the wrongdoing of his friend and had no idea the situation Pettyfer was in.
8 Friends: Seth Rogen And James Franco
Seth Rogen and James Franco have been friends for nearly twenty years. They met on the set of the short-lived but much-loved Freaks And Geeks in 1999 and have basically been attached at the hip ever since.
Rogen has written poems about their friendship and Franco credits his best friend with seeing him through some his career’s most trying times.
Similarly, Rogen fully believes it’s his relationship with Franco that has made him a happier actor and writer. He would often bounce ideas off his best friend, admitting to his insecurities over some of the more risky jokes.
Every time, Franco would show support, running with Rogen’s ideas, making them a reality, and bolstering his friend’s confidence in the process. Oh, and also Rogen thinks Franco makes the best pie-- and isn’t that what friendship is really about?
7 Hate: Miley Cyrus And Selena Gomez
Selena Gomez may still carry a great love for her Wizards Of Waverly Place co-stars, but the same can’t be said for Miley Cyrus, with whom she guest starred on Hannah Montana a few times.
Gomez and Cyrus have never been able to become good friends-- or even just friends. They have been at odds with each other for years.
For the most part, the two former Disney stars squabbled over boys. First Cyrus dated Nick Jonas, then Gomez did. After Gomez broke up with Justin Bieber, he was seen out and about with Cyrus.
Cyrus has made multiple public attacks against Gomez since, indicating a huge disliking between the two sometimes romantic rivals. Everything came to a head when the two ladies unfollowed each other on Twitter, and there’s no coming back from that.
6 Friends: Chris Pratt And Bryce Dallas Howard
Chris Pratt and Bryce Dallas Howard’s Jurassic World characters may not be very close, but these two actors are the best of friends and can’t help but share their love for each other with the world.
They hang out like regular besties, catching horror movies together and planning play dates. Rumors got out that the co-stars were feuding before filming for the franchise’s second installment, Jurassic World: Fallen Kingdom began, but they both rushed to Twitter to shut it down as soon as possible.
Howard informed the world that she “worshipped” Pratt, while Pratt swore he would “go to the mat” for her.
Well, it turns out that those play dates saved the day. Whether or not a feud actually took place between Pratt and Howard, it’s clearly a thing of the past.
The castmates recently dropped by to chat with Ellen Degeneres, where Pratt revealed his 5-year-old son’s massive crush on Howard’s 6-year-old daughter. The pair praised their children’s sweet friendship and swore that they would always be close.
5 Hate: Kevin Smith And Bruce Willis
Never meet your idols. That’s the message Kevin Smith was left with — and the one he tried so hard to impart on his own fans — after his unfortunate experience filming Cop Out with Bruce Willis.
Smith first hinted at the issues during a podcast, in which he said one cast member refused to participate in a marketing poster. He eventually gave more detail, saying it wasn’t the funny cast member, referring to Saturday Night Live and 30 Rock alum Tracy Morgan.
Smith referred to Morgan as “a f**king dream” but still refused to say outright who the trouble on set was. Over time he became more vocal about his experience with the movie icon, saying that Willis repeatedly refused to cooperate and or thank the entire cast and crew for their hard work and dedication.
4 Friends: Gal Gadot And Chris Pine
They had only just started out on their wild DCU ride, but Gal Gadot and Chris Pine became fast friends before Wonder Woman filming ever wrapped.
These two could be constantly seen joking around, laughing, and genuinely enjoying each other’s company. They seem to have an endless supply of inside jokes and Pine never tires of teasing Gadot for her linguistic faux pas.
Gadot revealed her and Pine’s secret to a strong friendship: he’s the male version of her. The two co-stars agreed on practically everything and would spend their downtime on set gabbing about fashion and clothes... girl talk, basically.
These buddies are so in sync that they totally ad-libbed the hilarious boat scene in which Steve Trevor gets a lesson in love and sex. Movie magic comes naturally to these two.
3 Hate: William Shatner And George Takei
William Shatner and George Takei have famously feuded for forty years. They hated each other on the set of Star Trek and still don't get along now. Though they have both tried to downplay their discontent at various points over the years, they have also been more than obvious about how much they dislike each other.
Takei blamed Shatner for changing scripts in order to downplay his character and requesting the director to focus the cameras on him instead of his castmates.. He also revealed that the majority of Shatner’s rants against his former co-star are always conveniently timed to coincide with his own projects.
Shatner accused Takei of having some sort of “sickness” inside him and taking everything out on him.
2 Friends: Anna Kendrick And Emily Blunt
Anna Kendrick was nervous about the acting powerhouses she would have to perform next to in Rob Marshall’s Into The Woods. She thought she wouldn’t measure up and she especially thought co-star Emily Blunt would be “British and icy.”
However, she was so wrong. Kendrick swore Blunt was a down-to-earth comedian who immediately became her best friend on the set.
Kendrick has praised Blunt’s self-deprecating humor and love of fart jokes. However, mostly she just super loves her best friend and thinks she’s the nicest lady she’s ever met.
When Kendrick and Blunt’s husband, John Krasinski, performed on Spike’s Lip Sync Battle, Kendrick made sure Krasinski knew just how she felt about his leading lady with a song, slideshow, and t-shirt dedicated to her love for Blunt.
1 Hate: Patrick Swayze And Jennifer Grey
Patrick Swayze was a total gentleman, so he never came right out and said what he thought of his Dirty Dancing co-star, Jennifer Grey. He would often speak highly of the actress, crediting her with the film’s success.
However, behind-the-scenes details revealed in his autobiography, The Time Of My Life, made it clear he wasn’t always a big fan of his much younger co-star’s antics.
Swayze revealed that after long work hours and freezing lake lifts, Grey would often become emotional, either breaking down and crying at the slightest criticism — or bursting out laughing, ruining takes and forcing them to repeatedly reshoot.
In fact, the adorable scene in which Grey’s Baby bursts out laughing during dance rehearsal wasn’t part of the script-- and neither was Swayze’s unenthusiastic reaction.
Can you think of any other cast mates who became the best of friends (or others who hated each other)? Sound off in the comments!
