This film reenacts the Manhattan Project, the secret wartime project in New Mexico where the first atomic bombs were designed and built.
The code names for the weapons - "Fat Man" and "Little Boy" - stem from characters in the written stories of writer Dashiell Hammett. Originally the names "Fat Man" and "Thin Man" were lifted directly from the stories, but the Thin Man weapon design (a Plutonium gun-type weapon) had to be abandoned. The relatively small Uranium gun-type weapon that followed was then named "Little Boy" as a contrast to "Fat Man".
Gen. Leslie R. Groves:
Gotta come down out of the clouds gentlemen, and get into the business... of winning the war.
The telegram to Oppenheimer states that Dr. Jean Tatlock committed suicide 5 January 1945. She actually committed suicide a year earlier, in January 1944.
