• Cillian Murphy plays J. Robert Oppenheimer in the new Christopher Nolan movie "Oppenheimer."
• It explores how the scientist created the world's first atomic bomb.

Christopher Nolan's latest movie, "Oppenheimer," sees Irish actor Cillian Murphy play J. Robert Oppenheimer, the man responsible for leading the Manhattan Project and creating the atomic bomb for the United States during World War II.

He's famously known for quoting the Hindu text, "The Bhagavad Gita," following the nuclear weapons test, saying: "Now I am become Death, the destroyer of worlds." But he later resigned from the Manhattan Project shortly after the US dropped nuclear bombs on Hiroshima and Nagasaki in Japan.

The film also looks at Oppenheimer's complex personal life, including his marriage to Katherine "Kitty" Oppenheimer, née Puening.
