Actor Cillian Murphy, who is gearing up for the release of his upcoming biopic, 'Oppenheimer', has shared that in order to prepare for the titular character and to get into its mindspace, he read Bhagavad Gita, the foundational text of Hinduism. The movie is based on the life of nuclear physicist J. Robert Oppenheimer who is widely regarded as the 'Father of the nuclear bomb', the film adapts the Pulitzer Prize-winning book American Prometheus by Kai Bird and the late Martin J. Sherwin. With a particular focus on the Trinity Test and the Manhattan Project which led to creation of the atom bomb, the movie also showcases the race against time of the Americans to finish building their bomb before Nazi Germany can complete theirs.

American nuclear physicist J. Robert Oppenheimer, who was the director of the Los Alamos Laboratory during World War 2, and is often credited as the "father of the atomic bomb" for his role in the Manhattan Project, learned Sanskrit at Berkley. "I have become death, the destroyer of worlds" is the most repeated quote of Oppenheimer. He borrowed it from Geeta.
