Following the first trailer released last December, the newest trailer for Christopher Nolan’s upcoming biopic, Oppenheimer, has been released, providing viewers with a further glimpse of what to expect from the film. The trailer sets a serious tone from the outset, diving into the creation of the first-ever nuclear bomb and the scientists responsible for it, including the film’s protagonist, J. Robert Oppenheimer, played by Cillian Murphy.

The trailer also showcases the talented cast, which includes Emily Blunt as Oppenheimer’s wife Kitty and Matt Damon as Lieutenant General Leslie Groves. The film’s cast is rounded out by a host of other well-known actors, including Robert Downey Jr., Florence Pugh, Rami Malek, Kenneth Branagh, and Gary Oldman, among others.

Oppenheimer is based on the biographical novel American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer and explores the physicist’s legacy as the inventor of the atomic bomb. The film follows Oppenheimer as he works alongside a team of government scientists to develop nuclear weapons in the early 1940s.

This project marks Murphy’s first time in a lead role for one of Nolan’s films, despite their past collaborations on movies like Inception and Dunkirk. In preparation for the film’s release, the British Film Institute has announced plans to re-release some of Nolan’s previous works in theaters, including The Dark Knight trilogy and Interstellar. Oppenheimer is set to hit theaters on July 21, offering a thought-provoking and intense exploration of one of the most significant scientific advancements of the modern era.
