In the early going of this marathon film, J. Robert Oppenheimer (Cillian Murphy) tells a hostile government committee that his testimony should be understood in the context of his life and work. Context also is important for movies, but Oppenheimer keeps key back stories off the screen.
Viewers see the “Hitler Invades Poland” headline from September 1, 1939, but do not see or hear anything about Josef Stalin’s Communist forces invading Poland on September 17, 1939. This joint invasion started WWII and came about because of the Stalin-Hitler pact of August 23, 1939. Viewers see nothing about the Pact, and no headline such as “Stalin Invades Finland,” marks November 30, 1939.
