Justin Chien spent years building his craft in short films and small television roles before Netflix cast him as Charles Sun, a role that turned him into one of the most talked-about new faces in Asian American television. His performance in The Brothers Sun opposite Michelle Yeoh showed off both his dramatic range and his martial arts training, and it led directly to his next major role: King Kuei in Season 2 of Avatar: The Last Airbender.
This article covers what’s confirmed about Justin Chien’s career, training, and upcoming projects, and it’s upfront about which personal details — his exact birthdate, family background, and net worth — are still unconfirmed and vary widely across the web.

Who Is Justin Chien?
Early Life and Family
Justin Chien is Taiwanese-American, and public reporting consistently ties his family background to Taiwan. Beyond that, claims about his exact birthplace, birth year, and family history vary so much across fan sites that none of them can be stated as fact here. What is well established is that he built his acting career the traditional way: short films, small festival wins, and modest TV roles before his Netflix breakthrough.
Taiwanese-American Heritage
Chien has spoken about his Taiwanese roots shaping how he approached playing Charles Sun, a character caught between Taiwanese family loyalty and life in Los Angeles. That dual perspective — someone who understands both cultures rather than performing one from the outside — is part of what made him a strong fit for the role.
Education and Acting Training
Chien trained in USC’s BFA program at the School of Dramatic Arts, where he took part in stage productions including a lengthy staging of The Kentucky Cycle. Alongside his acting classes, he studied editing, cinematography, and screenwriting, which explains why his career quickly expanded beyond acting into writing and producing.
Justin Chien’s Acting Career
Early Career and First Roles
Chien’s first screen credit was the 2015 short film Minolta. From there, he built a portfolio of independent work, including co-writing, co-producing, and co-directing the 2018 short Continuum, which was selected for the 2019 DisOrient Asian American Film Festival of Oregon. He also worked on the shorts Fine China and Endless Yesterdays, and took on television roles including a recurring part in Two Sides: Unfaithful.
Breakthrough with The Brothers Sun
Everything changed in January 2024, when Netflix released The Brothers Sun, an action-comedy created by Brad Falchuk and Byron Wu. Chien played Charles Sun, a trained assassin summoned home to Los Angeles to protect his family after his father is attacked in Taipei. The eight-episode season earned strong reviews and a loyal audience, with Rotten Tomatoes scores in the mid-to-high 80s from critics and low 90s from audiences.
Working with Michelle Yeoh
Chien starred alongside Oscar winner Michelle Yeoh, who played Eileen Sun, the family’s matriarch. Sharing scenes with an actress of Yeoh’s stature early in a career is rare, and reviewers pointed to the chemistry between the two as one of the show’s strengths.
Martial Arts Training and Action Skills
Chien brought real physical preparation to the role. He has trained in Muay Thai for roughly a decade and holds a blue belt in Brazilian Jiu-Jitsu, and that training let him handle much of his own stunt work in The Brothers Sun’s fight sequences rather than relying entirely on a double.
Netflix did not renew The Brothers Sun for a second season, announcing the cancellation in March 2024 despite the show’s positive critical reception. Chien addressed the decision publicly, saying he gave everything he had to the show and would carry that same commitment into whatever came next.
Role as King Kuei in Netflix’s Avatar: The Last Airbender
That “whatever came next” arrived quickly. In November 2024, Variety reported that Chien had joined Season 2 of Avatar: The Last Airbender as King Kuei, the ruler of the Earth Kingdom and Ba Sing Se. In a January 2026 interview, Chien described his take on the character as a departure from the animated original rather than a direct copy. Season 2 premiered on Netflix on June 25, 2026.
Other Movies and TV Shows
IMDb also credits Chien with a role in The Great Leap, alongside his short-film work. His filmography remains compact but purposeful, built around projects that let him stretch across genres rather than repeat the same type of role.
