Hollywood star Robert Downey Jr will be featuring in the series adaptation of author Viet Thanh Nguyen’s Pulitzer Prize-winning novel The Sympathizer, being developed by entertainment company A24 for HBO. The role would mark Downey Jr’s first major project after hanging up his Iron Man suit in Avengers: Endgame (2019).

According to reports, Old Boy helmer Park Chan-wook will be directing the drama series. He will also serve as co-showrunner with Don McKellar. The 2015 book is described as a cross-culture satire about the struggles of a half-French, half-Vietnamese communist spy during the final days of the Vietnam War and his resulting exile in the United States.
