Who Plays President Truman In Oppenheimer

Oppenheimer features many representations of historical figures, including some former Presidents. Christopher Nolan’s epic biopic chronicles the rise and fall of what the acclaimed director considers the most important person who ever lived, J. Robert Oppenheimer. The 3-hour movie follows his incredible successes as the head of the Manhattan Project in the creation of the atomic bomb and his unfortunate demise, which was largely at the hands of Lewis Strauss, played by Robert Downey Jr.
