Overview

DramaHistoryTV Movie

Hungarian physicist Leo Szilard leaves Europe, eventually arriving in the United States. With the help of Einstein, he persuades the government to build an atomic bomb. The project is given to no-nonsense Gen. Leslie Groves who selects physicist J. Robert Oppenheimer to head the Los Alamos Laboratory in New Mexico, where the bomb is built. As World War II draws to a close, Szilard has second thoughts about atomic weapons, and policy makers debate how and when to use the bomb.

Deep Dive

Trivia, insights & behind the scenes

Trivia

Made for TV but shot like a prestige feature—CBS spent $6 million in 1989, unheard of for television then.

Insight

Szilard's actual petitions were suppressed until after the war; the film's most dramatic moment was buried government history.
