Question: Day One starring David Strathairn as Dr. J. Robert Oppenheimer is a docu-drama movie about what research and development of the atomic bomb during WWII?
Context: Day One is a made-for-TV documentary-drama movie about The Manhattan Project, the research and development of the atomic bomb during World War II.  It is based on the book by Peter Wyden.  The movie was written by David W. Rintels and directed by Joseph Sargent.  It starred Brian Dennehy as General Leslie Groves, David Strathairn as Dr. J. Robert Oppenheimer and Michael Tucker as Dr. Leo Szilard.  It premiered in the United States on March 5, 1989 on the CBS network.  It won the 1989 Emmy award for Outstanding Drama/Comedy Special.  The movie received critical acclaim for its historical accuracy despite being a drama. Good Night, and Good Luck is a 2005 American historical drama film directed by George Clooney and starring David Strathairn, George Clooney, Robert Downey, Jr., Patricia Clarkson and Jeff Daniels.  The movie was written by Clooney and Grant Heslov (both of whom also have acting roles in the film) and portrays the conflict between veteran radio and television journalist Edward R. Murrow and U.S. Senator Joseph McCarthy of Wisconsin, especially relating to the anti-Communist Senator's actions with the Senate Permanent Subcommittee on Investigations. American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer is a biography of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin published by Alfred A. Knopf in 2005.  Twenty-five years in the making, the book was awarded the 2006 Pulitzer Prize for Biography or Autobiography.  It also won the 2008 Duff Cooper Prize, Chicago Tribune Best Book of the Year, and "Discover Magazine" Best Science Book of the Year. Julius Robert Oppenheimer (April 22, 1904 – February 18, 1967) was an American theoretical physicist and professor of physics at the University of California, Berkeley.  Oppenheimer was the wartime head of the Los Alamos Laboratory and is among those who are credited with being the "father of the atomic bomb" for their role in the Manhattan Project, the World War II undertaking that developed the first nuclear weapons used in the atomic bombings of Hiroshima and Nagasaki.  The first atomic bomb was detonated on July 16, 1945, in the Trinity test in New Mexico; Oppenheimer later remarked that it brought to mind words from the "Bhagavad Gita": "Now I am become Death, the destroyer of worlds." Fat Man and Little Boy (a.k.a. Shadow Makers in the UK) is a 1989 film that reenacts the Manhattan Project, the secret Allied endeavor to develop the first nuclear weapons during World War II.  The film is named after the weapons "Little Boy" and "Fat Man" that were detonated over Hiroshima and Nagasaki, respectively.  The code names, originally Fat Man and Thin Man, were drawn from characters in the works of Dashiell Hammett.  However, there's a possible secondary allusion to stout project director Gen. Leslie Groves and the slim scientific director, Dr. J. Robert Oppenheimer.  The film focuses much attention on the frequently strained relationship between the two men. The J. Robert Oppenheimer Memorial Prize and Medal was awarded by the Center for Theoretical Studies, University of Miami, from 1969.  Established in memory of US physicist J. Robert Oppenheimer, the award consisted of a medal, certificate and a $1000 honorarium.  It was awarded for "outstanding contributions to the theoretical natural sciences [...] during the preceding decade". The Oppenheimer security hearing was a 1954 proceeding by the United States Atomic Energy Commission (AEC) that explored the background, actions, and associations of J. Robert Oppenheimer, the American scientist who had headed the Los Alamos Laboratory during World War II, where he played a key part in the Manhattan Project that developed the atomic bomb.  The hearing resulted in Oppenheimer's Q clearance being revoked.  This marked the end of his formal relationship with the government of the United States, and generated considerable controversy regarding whether the treatment of Oppenheimer was fair, or whether it was an expression of anti-Communist McCarthyism. The uranium hydride bomb was a variant design of the atomic bomb that was first suggested by Robert Oppenheimer in 1939 and advocated and tested by Edward Teller.  It used deuterium, an isotope of hydrogen, as a neutron moderator in a U235-deuterium compound.  The chain reaction is a slow nuclear fission (see neutron temperature).  Bomb efficiency is very adversely affected by the cooling of neutrons since it delays the reaction. The Day After Trinity (a.k.a.  The Day After Trinity: J. Robert Oppenheimer and the Atomic Bomb) is a 1980 documentary film directed and produced by Jon H. Else in association with KTEH public television in San Jose, California.  The film tells the story of J. Robert Oppenheimer (1904–1967), the theoretical physicist who led the effort to build the first atomic bomb, tested in July 1945 at Trinity site in New Mexico.  Featuring candid interviews with several Manhattan Project scientists, as well as newly declassified archival footage, "The Day After Trinity" was nominated for an Academy Award for Best Documentary Feature of 1980, and received a Peabody Award in 1981. George Aristotle Economou (June 24, 1923 – April 2, 2003) was an American optical systems expert, who helped set up special cameras to photograph and study the first test of the atomic bomb in 1945.  He was instrumental in the development of the atomic bomb at Los Alamos, working on the Manhattan Project under scientific director Robert Oppenheimer.
