Sandra Oh will join HBO.

The Emmy winner, who concluded production on AMC’s Killing Eve earlier this year, has joined the cast of the drama series The Sympathizer on the premium cable network. Kieu Chinh and Nguyen Cao Dy Duyen are also on board the Robert Downey Jr.-executive-produced drama. Each member of the three will have ongoing roles.

The Sympathizer is a cross-cultural satire and espionage thriller that will premiere in July 2021. It centers on the Captain, a Communist spy who is half French and half Vietnamese who operated during the last stages of the Vietnam War and was exiled to the United States as a result.

The series, which is based on the Pulitzer Prize-winning novel by Viet Thanh Nguyen, is produced by A24.

As the Captain, Hoa Xuande (Cowboy Bebop) is joined by fellow Vietnamese-American performers Fred Nguyen Khan, Toan Le, Vy Le, and Alan Trong. An extended search for actors in North America, Vietnam, Europe, and Australia led to the casting after a global open call. In The Sympathizer, Downey will play a variety of characters.
