Fail-Safe is a bestselling American novel by Eugene Burdick and Harvey Wheeler. The story was initially serialized in three installments in the Saturday Evening Post, on October 13, 20, and 27, 1962, during the Cuban Missile Crisis. The novel was released on October 22, 1962, and was then adapted into a 1964 film of the same name directed by Sidney Lumet and starring Henry Fonda, Dan O'Herlihy, and Walter Matthau. In 2000, the novel was adapted again for a televised play, broadcast live in black and white on CBS. All three works have the same theme, accidental nuclear war, with the same plot.
