15 Times Actors Held Nothing Back And Name-Dropped The Worst Costar They've Ever Worked With

Like any other employees, actors are expected to act professionally. Sometimes, however, they leave their costars with a bad taste in their mouth.

Here are 15 times actors name-dropped their worst costars:

1. In 2014, Freddie Prinze Jr . told ABC News , "I did 24 . It was terrible. I hated every moment of it. Kiefer [Sutherland] was the most unprofessional dude in the world. That's not me talking trash, I'd say it to his face. I think everyone that's worked with him has said that. I just wanted to quit the business after that. So, I just sort of stopped."

2. In 2016, Diane Kruger told BuzzFeed that her Troy costar Peter O'Toole "wasn't very pleasant."

3. In 2020, Samantha Marie Ware replied to a tweet her Glee costar Lea Michele made about the death of George Floyd and the Black Lives Matter movement. Samantha said, "LMAO REMEMBER WHEN YOU MADE MY FIRST TELEVISON GIG A LIVING HELL?!?! CAUSE ILL NEVER FORGET. I BELIEVE YOU TOLD EVERYONE THAT IF TOU HAD THE OPPORTUNITY YOU WOULD 'SHIT IN MY WIG!' AMONGST OTHER TRAUMATIC MICROAGRESSIONS THAT MADE ME QUESTION A CAREER IN HOLLYWOOD."

4. On a 2023 episode of her podcast Bitch Sesh , Casey Wilson said that her The Santa Clauses costar Tim Allen was "such a bitch" to work with. She also said it was the "worst, truly single worst experience [she's] ever had with a costar ever."

5. In an Instagram story ahead of the release of her 2024 memoir Rebel Rising , Rebel Wilson alleged that an "asshole" celebrity was "trying to threaten" her over a chapter and "trying to stop press coming out about [her] new book." The next day, she revealed the "asshole" in question was her The Brothers Grimsby costar Sacha Baron Cohen.

6. In 2000, Lucy Liu stood up to Bill Murray on the Charlie's Angels set, and in 2021, the resurfaced story went viral. She told the Los Angeles Times' Asian Enough podcast, "As we're doing the scene, Bill starts to sort of hurl insults, and I won't get into the specifics, but it kept going on and on. I was like, 'Wow, he seems like he's looking straight at me.' I couldn't believe that [the comments] could be towards me, because what do I have to do with anything majorly important at that time? I literally do the look-around-my-shoulder thing, like, who is he talking to behind me? I say, 'I'm so sorry. Are you talking to me?' And clearly he was, because then it started to become a one-on-one communication."

7. In his 2014 memoir Neil Patrick Harris: Choose Your Own Autobiography , Neil Patrick Harris reportedly called his Purple People Eater costar Dustin Diamond "one of the more unpleasant people in show business."

8. In 2016, Viola Davis told Entertainment Weekly that her Suicide Squad costar Jared Leto — who stayed in character as the Joker — gifted her a box of bullets. She said, "It was a little worrisome. It made you a little bit nervous, and I'm pretty tough. You know, I got into a few fights when I was growing up…but it scared me a little bit."

She also said she didn't meet the "real" Jared until filming wrapped.

She said, "Before that, I was only introduced to the Joker…and I almost had my pepper spray out. You know, 'You remember that bullet you sent me?'"

9. In 2007, Tyrese Gibson told Elle , "[My Annapolis costar] James Franco is a Method actor. I respect Method actors, but he never snapped out of character. Whenever we'd have to get in the ring for boxing scenes, and even during practice, the dude was full-on hitting me. I was always like, 'James, lighten up, man. We're just practicing.' He never lightened up."

10. In 2018, Alice Wetterlund tweeted , "I hope to not ruin it for you, but [my Silicon Valley costar] TJ Miller was a bully and petulant brat and pretty much everyone who had any power on that (almost all male) set, including the male cast members, enabled him and were complicit in his unprofessionalism. They can fuck off forever."

11. On Community , Chevy Chase reportedly made frequent attempts to disrupt Donald Glover's scenes by making racial jokes out of jealousy. In 2018, Donald told the New Yorker , "I don't even worry about it. I just saw Chevy as fighting time — a true artist has to be okay with his reign being over. I can't help him if he's thrashing in the water. But I know there's a human in there somewhere — he's almost too human."

12. Appearing on the radio show No Filter Neha in 2020, Taapsee Pannu reportedly said one of her worst co-stars was Jacqueline Fernandez. She said, "She has [a] so freaking hot body because I was struggling to match up to her in Judwaa 2. "

She continued, "I was just like I just hope that I don’t put myself to shame."

13. On No Filter Neha , Taapsee Pannu also name-dropped her Manmarziyaan and Dunki costar Vicky Kaushal as one of her worst costars.

14. In 1993, Julia Roberts told the New York Times her I Love Trouble costar Nick Nolte was "completely disgusting." She said, "He's going to hate me for saying this, but he seems [to] go out of his way to repel people. He's a kick."

15. And finally, in 2017, Kim Cattrall called out her Sex and the City costar Sarah Jessica Parker amidst the cancellation of SATC 3 . On the ITV series Life Stories , she told Piers Morgan, "I don't feel like a victim. I feel like I came out of this on top. This has given me a fantastic platform. Sarah Jessica, she could have been nicer, she could have in some way. I don't know what her issue is. I never have."
