• Cillian Murphy plays J. Robert Oppenheimer in Christopher Nolan's "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 was met with huge critical acclaim, earning five awards at the 2024 Golden Globes, including best picture. It also won seven awards at the 2024 BAFTAS, with Cillian Murphy and Robert Downey Jr. taking home awards for best actor and best supporting actor, respectively.

As well as Oppenheimer's nuclear work, the film looks at the scientist's complex personal life, including his marriage to Katherine "Kitty" Oppenheimer, née Puening.
