Oppenheimer new trailer: Cillian Murphy, Robert Downey Jr. lead the historical epic about the first atomic bomb

Through the biographical drama Oppenheimer, filmmaker Christopher Nolan attempts to trace a momentous period of renowned American theoretical physicist J. Robert Oppenheimer. Set against the backdrop of World War II, the film chronicles how the United States of America employs Robert Oppenheimer to lead the Los Alamos Laboratory, a secret laboratory where the world's first atomic bomb was created.

Nolan also endeavours to shed light on the moralistic implications of the creation of the nuclear weapon which, although proved to be an accessory at the time for the fight against the Nazis, later ended up posing moral and ethical questions to its creators. Cillian Murphy stars in the titular role and the principal cast of Oppenheimer also includes Matt Damon, Emily Blunt, Robert Downey Jr., Rami Malek, Florence Pugh, Benny Safdie, Michael Angarano, Josh Hartnett and Kenneth Branagh.

The new and second trailer of the film, which was released on May 8, offers a glimpse into J. Robert Oppenheimer's intense pursuits to conceive and design the weapon of mass destruction before the enemies do. Matt Damon's Major General Leslie Groves, who served as the director of the Manhattan Project, is shown to be another integral element of the process as he goes against the odds to help Oppenheimer put together a facility in the middle of nowhere. Emily Blunt plays Katherine "Kitty" Oppenheimer, the wife of J. Robert Oppenheimer, and Christopher Nolan's narrative lays as much focus on their relationship during this significant period in American history.

Christopher Nolan, who has also written the film, derives the material from Kai Bird and Martin J. Sherwin's non-fiction book 'American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer'. While the biographical novel delves deep into the early life, ambitions and ideas of the physicist and paints a vast picture of his life, it would be interesting to see how Nolan condenses the 721 pages long book into a 2-hour-and-30-minute-long feature film. 

Hoyte van Hoytema returns as the cinematographer with Tenet composer Ludwig Göransson scoring the music. Oppenheimer will arrive in cinema halls worldwide on July 21, 2023.
