We’ve all seen characters fall in love onscreen; we’ve also seen characters become mortal enemies. Such is the way of the Hollywood film set, where conflict is key.
But sometimes we forget that those characters are real people offscreen, too, and they’re capable of forming never-ending friendships and fiery conflicts in the real world. And, sometimes, these conflicts and friendships are more exciting than any onscreen tension!
So, let’s take a look at 10 of the most friendly—and 10 of the most fiery—costar relationships in Hollywood…
1. Friends: Sophie Turner and Maisie Williams: The Stark sisters may have a history of squabbling in the world of Westeros, but offscreen, these Game of Thrones stars are inseparable. They often chronicle their real-life adventures together through lively social media posts.

2. Enemies: Rachel McAdams and Ryan Gosling: Despite their famous onscreen chemistry, this Hollywood pair was feuding big time on the set of The Notebook. Tension between them was so bad that Gosling asked the director for a new costar, but eventually, the two worked their problems out, even dating for three years afterward.

3. Friends: Amy Poehler and Tina Fey: First meeting in a Chicago improv group, these funny ladies skyrocketed into mega-stardom as hosts of Saturday Night Live’s Weekend Update. Even with successful individual careers, Fey and Poehler continue working together to create hit comedy films.

4. Enemies: Wesley Snipes and Ryan Reynolds: Reports from the set of Blade: Trinity show Snipes wasn’t the easiest to work with. Snipes frequently insulted costar Reynolds and he refused to speak with the film’s director.

5. Friends: Dane Dehaan and Daniel Radcliffe: Radcliffe and Dehaan met on the set of Kill Your Darlings, a film chronicling major writers in the beat generation. Afterwards, the Harry Potter star spoke highly of Dehaan, claiming he was the best friend he made since he started acting. Move over, Ron and Hermione!

6. Enemies: Josh Hartnett and Harrison Ford: These two starred in Hollywood Homicide, a film universally reamed by critics—and the touchy relationship of its stars certainly didn’t help matters. Ford and Hartnett hardly spoke through the entire production.

7. Friends: James Franco and Seth Rogen: They met on the set of Freaks and Geeks, and ever since, these two have entered into a torrid bromance. While the megastars have since diverged into successful separate careers, their friendship lives on offscreen.

8. Enemies: Lena Headey and Jerome Flynn: You don’t see Bronn of the Blackwater and Cersei Lannister share much screen time in the HBO series Game of Thrones, and maybe that’s for the better. These former romantic partners refuse to shoot scenes with one another—or even be on the same set, for that matter.

9. Friends: George Clooney and Brad Pitt: Both A-list actors and A-list heartthrobs, Clooney and Pitt’s offscreen dynamic has led to massive onscreen successes, including hit films such as Ocean’s Eleven. The two have also been ensnared in a multi-year prank war that doesn’t look like it will end any time soon.

10. Enemies: William Shatner and George Takei: Rumor has it that Shatner’s ego on the set of Star Trek had its own gravitational pull, and that’s precisely what led to friction with costar Takei. The feud has persisted for nearly 40 years.

11. Friends: Matt Damon and Ben Affleck: This duo rocked Hollywood with their debut film, Good Will Hunting, and they continue to find creative success together years later. Though they haven’t appeared onscreen together since 1999, that hasn’t stopped the two from working behind the scenes on multiple endeavors.

12. Enemies (then friends): Harold Ramis and Bill Murray: Murray doesn’t seem like the type to make enemies, but on the set of Groundhog Day, after a rough divorce that made him temperamental, he and his Ghostbusters costar had a conflict that led to the end of their friendship. It wasn’t until shortly before Ramis’ death in 2014 that the two were able to make up.

13. Friends: Tobey MacGuire and Leonard DiCaprio: These two share a bond that developed before either found major Hollywood success, as both of these current megastars fought to break onto the big screen without the help of a father figure.
"Great Gatsby" / Warner Bros.
14. Enemies (sort of): Richard Dreyfuss and Robert Shaw: On the set of Jaws, the story goes that Shaw often intimidated and ridiculed Dreyfuss. Oddly, Dreyfuss noted that Shaw was perfectly amicable offset. The feud mirrored the conflict between each actor’s respective characters in the movie, leaving some to speculate that Shaw was trying to get the tension just right for the cameras.

15. Friends: Cameron Diaz and Drew Barrymore: These actresses met in their mid-teens, but their friendship really kicked off once they started filming for Charlie’s Angels. Their friendship is so strong that each served as a bridesmaid in the other’s wedding.

16. Enemies: Cybil Shepard and Bruce Willis: The 1980s dramedy Moonlighting featured an intense will-they/won’t-they relationship between Willis and Shepard’s characters, but the romance stopped there. The two did not get along offscreen, but hey, maybe that conflict added realism to their onscreen scenes?

17. Friends: Artie Lange and Norm MacDonald: After meeting on the set of the feature Dirty Work, this duo became fast friends. Besides the similar sense of humor, MacDonald noted it was also the struggles they shared that brought them together.
"Dirty Work" - MGM
18. Enemies: Bill Murray and Lucy Liu: Here’s yet another enemy of Murray’s. The feud began on the set of Charlie’s Angels when Murray complained about Liu’s acting techniques. Liu fired back, and a conflict was born.
"Charlie's Angels" - Columbia Pictures
19. Friends: Dan Aykroyd and John Belushi: Like Amy Poehler and Tina Fey, this legendary duo emerged from the Chicago improv scene, finding massive success as SNL‘s Blues Brothers. Both actors were known for employing a serious approach toward the art of comedy.
"Blues Brothers" - Universal
20. Enemies: Bette Davis and Joan Crawford: These two shared a conflict of such epic proportions that an entire FX miniseries couldn’t chronicle every dispute between them. Each conspired to sabotage the other’s personal lives and careers. Somehow, they channeled their conflict into a successful psychological drama, Whatever Happened to Baby Jane?

Conflicts, romances, and friendships have dominated just about every Hollywood era—some for the better, and some decidedly for the worse. But as long as Hollywood keeps producing films and television, you’d better believe that the list of friends and enemies will continue to grow!
