Robert Downey Jr. has won the Oscar for Best Supporting Actor at the 2024 Academy Awards for his role in Oppenheimer, the first Oscar for Christopher Nolan's latest film.

In Oppenheimer, Downey Jr. played Lewis Strauss, the former chairman of the Atomic Energy Commission who masterminded the hearing that revoked J. Robert Oppenheimer's (Cillian Murphy) security clearance. The past few months have been a banner award season for the star, who took home the Golden Globe, SAG Award, Critics Choice Award, and BAFTA for his masterful performance of Oppenheimer's duplicitous former colleague.
