Fat Man and Little Boy
1989, English. Directed by Roland Joffé.
The story of the extraordinary people who changed our world.
Assigned to oversee the development of the atomic bomb, Gen. Leslie Groves is a stern military man determined to have the project go according to plan. He selects J. Robert Oppenheimer as the key scientist on the top-secret operation, but the two men clash fiercely on a number of issues. Despite their frequent conflicts, Groves and Oppenheimer ultimately push ahead with two bomb designs — the bigger "Fat Man" and the more streamlined "Little Boy."
