Season 3 of The White Lotus, much like every installment, has been a wild ride for viewers. The hit HBO anthology series has seen an incestuous, drug-induced threesome unravel; a catty trio of delusional blondes shit-talk each other into oblivion; and a jaw-dropping, midlife-crisis monologue from yet another white man in his 50s. Suffice to say, it’s been full of drama—and the spectacle will only reach its head during Sunday’s finale.

Although sunning in gorgeous Thailand for six and a half months among a star-studded group of creatives sounds idyllic, there was apparently just as much drama off-screen once the cameras were cut. Jason Isaacs, who plays Southern financier dad Timothy Ratliff, unwittingly spilled the beans on troublesome cast dynamics behind the scenes.

Troubles Among the Cast

“It was like a cross between summer camp and Lord of the Flies but in a gilded cage,” he said during an interview with Vulture. “It wasn’t a holiday. Some people got very close. There were friendships that were made and friendships that were lost.”

He continued, explaining, “All the things you would imagine with a group of people unanchored from their home lives on the other side of the world, in the intense pressure cooker of the working environment with eye-melting heat and insects and late nights. They say in the show, ‘What happens in Thailand stays in Thailand,’ but there’s an off-screen White Lotus as well, with fewer deaths but just as much drama.”

When asked to give specifics about the issues, Isaacs responded,  “Absolutely not. I became very close to some people and less close to others, but we still all had that experience together and there’s a certain level of discretion required.”

If The White Lotus press tour is any indication, it looks like the Harry Potter alum formed strong bonds with his on-screen kids Patrick Schwarzenegger, Sarah Catherine Hook, and Sam Nivola. The four even took a trip to New York City together recently.

“When we first got there, we took over the Four Seasons Koh Samui. You can’t have paying guests when there’s a film crew there, so I got a huge villa to myself with a full-sized pool and a butler,” he told The Hollywood Reporter. “It’s fabulous to FaceTime your friends and show off, but I was also really lonely. The kids—Patrick, Sam and Sarah Catherine—came to my rescue.”

In the same interview, Walton Goggins, who plays the brooding Rick, said he felt isolated from the rest of the cast because of his role.

“I felt misunderstood, like I was a fucking downer for everyone else,” Goggins explained. “I was just consumed by the story. It got to a place where they would just put my chair somewhere different on set or I’d sit on a rock away from everybody and wait for the weekends to hang out with people. But Aimee (Lou Wood) and I became very close, very quickly, and a part of that was because when everyone else was like, ‘Oh, just leave that guy alone,’ Aimee constantly came and poked me.”

Leslie Bibb, who plays likely Trump supporter Kate, said, “I knew with Walton how all-consuming it had been—and painful.” Though, she added, Sam Rockwell joining the cast offered Goggins some levity, as the two are good friends.

In the same interview, Carrie Coon, who plays divorced lawyer Laurie, said filming the show wasn’t as picture-perfect as it may sound.

“People have an idea about what it’s like to do The White Lotus—that it’s glamorous—and they’re wrong. It’s way more like working in a regional theater in Wisconsin, where you’re showing up in a new town every day. We moved 12 times or something. We were living out of suitcases,” The Leftovers alum explained.

Though it doesn’t seem all bad. Natasha Rothwell, who plays empathetic masseuse Belinda, chimed in, adding, “There’s a lot of sharing and caring that goes on because you’ve become this weird, beautiful family.”

Composer Cristobal Tapia de Veer Exits the Show

While it is unknown who within the cast had a falling out, composer Cristobal Tapia de Veer revealed to The New York Times that he will not be returning to season 4 due to ongoing creative differences with creator Mike White. Tapia de Veer explained that he disagreed with White’s music ideas from the start. As a result, the composer developed the mantra, “How do I pass all this weird music into the show?” for his process.

He also explained that upon receiving fan backlash for the season 3 theme song, he texted the one of the show’s producers to discuss releasing a longer version of the original theme song.

“He thought it was a good idea. But then Mike cut that. He wasn’t happy about that,” Tapia de Veer said. “I mean, at that point, we already had our last fight forever, I think. So he was just saying no to anything. So I just uploaded that to my YouTube.”

He concluded by saying, “I was watching the Emmys, and it’s like, there’s one thing I’m pretty proud of and that is I feel like I never gave up. Maybe I was being unprofessional, and for sure, Mike feels that I was always unprofessional to him because I didn’t give him what he wanted. But what I gave him did this, you know—did those Emmys, people going crazy.”
