The Manhattan Project is a 1986 American science fiction thriller film. Named after the World War II-era program that constructed the first atomic bombs , the plot revolves around a gifted high school student who decides to construct an atomic bomb for a national science fair.
The formerly secret project was made public by the Smyth Report. In the immediate postwar years, the Manhattan Project assisted weapons testing in Operation Crossroads. It maintained control over American atomic weapons research and production until January 1947, when the Atomic Energy Act of 1946 took effect.
The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (about $35.4 billion in 2023 [1] dollars). Over 90% of the cost was for building factories and producing the fissionable materials , with less than 10% for development and production of the weapons.
