‘3 Body Problem’ season 2: Everything we know so far

After years of anticipation, sci-fi series “3 Body Problem” debuted as one of the most popular series on Netflix, generating huge buzz among both audiences and critics. It boasts a 79% “fresh” rating with critics at Rotten Tomatoes, and an equally impressive 77% audience score. TG’s Malcolm McMillan called it “the best show of 2024 so far.”

“Game of Thrones” creators David Benioff and D.B. Weiss seem to have found their perfect follow-up with this adaptation of Chinese author Cixin Liu’s acclaimed novel trilogy, co-created with Alexander Woo.

It was no surprise, then, that Netflix announced in May that the show would return for another season. Initially announced simply as "additional episodes," it was later clarified that the renewal would cover two more seasons to complete the adaptation of Liu's books. With that long-term plan in place, here's everything we know so far about "3 Body Problem" season 2.

'3 Body Problem' season 2 release date window

Given that the renewal was only recently announced, and the exact episode count for the next two seasons has yet to be determined, it's safe to say that it will be a while before "3 Body Problem" fans get to see any new episodes. Benioff, Weiss and Woo are just beginning to break the story with their writing staff, and both production and post-production on an epic, effects-heavy show like "3 Body Problem" take quite a long time. It was two and a half years between the time that production began on the first season and when it finally premiered on Netflix.

Even with writing underway and the possibility for the production process to be expedited thanks to the show's popularity, don't expect to see another season of "3 Body Problem" on Netflix until late 2025 at the earliest. Spring 2026, which would be two years after the premiere of the first season, seems like a stronger probability.

'3 Body Problem' season 2 cast

One thing that "3 Body Problem" has in common with "Game of Thrones" is its willingness to kill off major characters, which means that many of the main cast members from the first season will not return for future episodes (barring potential flashbacks). Liu's novels jump forward across significant periods of time, so it's possible that new actors may step in to play existing characters as well.

Characters who appear in the later books in the trilogy are likely to show up on the series in some form, although they may be changed significantly, just as the characters in the first season were substantially altered from the versions in the books.

For now, here are the series regulars from the first season whom we expect to show up again in "3 Body Problem" season 2.

• Jovan Adepo as Dr. Saul Durand

• Liam Cunningham as Thomas Wade

• Eiza González as Dr. Augustina "Auggie" Salazar

• Jess Hong as Dr. Jin Cheng

• Marlo Kelly as Tatiana Haas

• Sea Shimooka as Sophon

• Saamer Usmani as Prithviraj "Raj" Varma

• Benedict Wong as Clarence Shi

'3 Body Problem' season 2 plot

The first season of “3 Body Problem” ends with some pretty major open questions, so it seems likely that the second season will pick up there, to address the immediate resolutions to those cliffhangers. Liu’s novels span a period of hundreds of years, though, so there’s potential for the second season of “3 Body Problem” to expand its sci-fi world even further, with a grand, universe-spanning story of space travel and intergalactic conflict.

Benioff, Weiss and Woo have grounded Liu’s story in personal relationships to a greater degree than in the novels, and the story is likely to continue focusing on those relationships even as its scope expands across time and space. There’s the opportunity to add new characters as the story evolves, and the creators have also shown that they’re willing to make changes to Liu’s story in order to reach their target audience.

Benioff, Weiss and Woo have plenty of ideas for more seasons of “3 Body Problem,” and there’s a wealth of material left to adapt from Liu’s subsequent novels. “We included a lot of what we loved from the [novels] in season 1, but the vast majority of reasons we wanted to make this show are in season 2,” Weiss told Netflix's Tudum. “We always wanted to get to the final page of the third book, and it’s really, really thrilling to us that we will get to do just that.”

At one time, the creators indicated that they envisioned four seasons to tell the entire story, but now that the show is confirmed to last for three seasons, they're confident that they'll be able to bring it to a satisfying close in that amount of time. “We knew going into this how many hours we need to tell the rest of the story because we’ve got a roadmap through to the end,” Weiss told The Hollywood Reporter. “And we have what we need to get to the end as intended from when we started.”
