Blunt will play Katherine “Kitty” Oppenheimer , wife of the scientist. Downey Jr. will play Lewis Strauss , the infamous head of the Atomic Energy Commission who initiated hearings to question Oppenheimer ‘s loyalty to the United States of America, and had his license revoked. Damon will play General Leslie Groves , director of the Manhattan Project . Florence Pugh will play Jean Tatlock , psychiatrist and Communist Party member with whom Oppenheimerhad an affair (he proposed marriage to her twice, but she refused).
