Meet the cast of 3 Body Problem on Netflix

While the episodes are sure to keep viewers gripped by premise alone, the series also boasts a stellar ensemble cast and features some surprising appearances from well-known faces too including Jim Howick (Ghosts), Mark Gatiss (Doctor Who) and more.

The series is based on the novel by Liu Cixin and has been adapted by Game of Thrones writers David Benioff and DB Weiss alongside Alexander Woo.

Throughout the eight-parter, we follow a group of five scientists who team up with a detective when the world around them stops following the laws of nature. Facing an unknowable threat, they have to do everything they can to save humanity.

The main cast includes Jess Jong, John Bradley and Jonathan Pryce, as well as Eiza González, Alex Sharp and more.

Recently, creators Benioff, Weiss and Woo opened up about the global cast of characters, which is a big change from the books, as they're very much focused on China.

Woo explained to RadioTimes.com: "The opportunity that [the story] afforded us was that was that we could tell a story about humanity facing a global existential threat from an extraterrestrial civilisation, and if we're going to represent humanity, we should represent all of humanity."

He added: "That that led to the design of the cast being people who are representative of all of the world, with an African American character, Latin American character, characters of Oceania, South Asia, East Asia, Europe, and just about everywhere. That, I think, better represents the world than if we had kept everyone in the People's Republic of China."

Read on for more information about each of the characters and every actor in the show.

Jess Hong plays Jin Cheng

Who is Jin Cheng? Jin is a highly intelligent, no-nonsense scientist who has big ambitions. She's fiercely loyal but sometimes struggles to communicate with those she loves. When she puts her mind to something, she'll see it through to the bitter end.

Speaking to RadioTimes.com about Jin, Hong said: "I think it was genius that the guys split up Wang Miao into the Oxford Five so that you end up not with just one removed, really smart character but five - sure, geniuses, but very relatable, flawed characters for the audience to relate to on the whole journey.

"The first time I met [the creators] was on Zoom...they were all so laid back, they were all super chill, and they just wanted to get to know me."

She added: "What they do is they take your little mannerisms and your accent sometimes and they fold it into the character. Jin was never meant to have a Kiwi accent and yet she does. Jin never said, 'Hey buddy' a lot in the scripts before and now she does. I learn that about myself!"

Where have I seen Jess Hong before? Hong's first on-screen credit was in 2019 in the short film Krystal. Since, she's appeared in the TV series The Brokenwood Mysteries and Inked.

Speaking to RadioTimes.com about the character, actor Sharp said: "It’s such a simple thing, it’s about a man who loves a woman more than anything else in the world and what he’s willing to do for her.

"It was very simple and very moving and was quite abstract in playing the scenes, because Will’s not getting involved with the aliens – well, I’m hitchhiking a ride now!"

"I think making people care is one of the most under-respected and hardest things you can do across the board when it comes to film and TV.
