Fat Man and Little Boy
Fat Man and Little Boy (released in the United Kingdom as Shadow Makers) is a 1989 war film directed by Roland Joffé who co-wrote the script with Bruce Robinson. The story follows the Manhattan Project, the secret Allied endeavor to develop the first nuclear weapons during World War II. The film is named after "Little Boy" and "Fat Man", the two bombs dropped on the Japanese cities of Hiroshima and Nagasaki respectively.
In September 1942, U.S. Army Corps of Engineers Colonel Leslie Groves (Paul Newman) who oversaw construction of the Pentagon is assigned to head the ultra-secret Manhattan Project, to beat the Germans, who have a similar nuclear weapons program.
