For his first role since winning an Oscar, Robert Downey Jr. plays not one, not two, not three, but four different characters in The Sympathizer.

The HBO limited series, from brilliant Decision to Leave, The Handmaiden, and Oldboy filmmaker Park Chan-wook, is described as “an espionage thriller and cross-culture satire about the struggles of a half-French, half-Vietnamese communist spy during the final days of the Vietnam War and his new life as a refugee in Los Angeles, where he learns that his spying days aren’t over.” Hoa Xuande is in the lead role, while Downey Jr. plays a CIA operative, a professor, a congressman, and a movie director.
