A new teaser for Christopher Nolan’s Oppenheimer has debuted, providing fans a glimpse of the star-studded ensemble, which includes Cillian Murphy.
In the film, the stakes are clearly extremely high, as mysterious scientist J. Robert Oppenheimer (Murphy) must risk destroying the world in order to rescue it with his development of the atomic bomb.
Last summer’s teaser trailer may have focused more on taglines for Oppenheimer and his task as ‘the man who moved the earth,’ but this time the key players and their plans are more fully introduced to audiences, including Matt Damon, Emily Blunt, Florence Pugh, Sir Kenneth Branagh, and Robert Downey Jr.
Despite speculations to the contrary, Oppenheimer will be released on July 21, providing cinemagoers with a lovely feast of film alongside Margot Robbie and Ryan Gosling in Greta Gerwig’s Barbie, which is also released on the same day.
‘This is a national emergency,’ Murphy as Oppenheimer is heard saying, as the team gears up its equipment at the start of the trailer for the film, which is based on Kai Bird and Martin J Sherwin’s Pulitzer Prize-winning book, American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer.
‘We’re in a race against the Nazis – and I know what it means if the Nazis have a bomb,’ he adds in an urgent warning.



Damon next appears as General Leslie Groves Jr., the Manhattan Project director who assisted Oppenheimer in recruiting scientists for the secret Los Alamos Laboratory, commonly known as Project Y.
‘Build a town, and build it quickly. We don’t want scientists to bring their families because we’ll never get the best.’ Oppenheimer proceeds to build the isolated New Mexico site, and his scientist and botanist wife Kitty (Blunt) is seen driving towards it.
Oppenheimer is seen in an encounter with Albert Einstein, with Groves arguing it’s the’most significant event to ever happen in the history of the planet’ as they try to influence people to their cause.
Groves then wrestles with the reality that, according to Oppenheimer, the chances of the world being destroyed are only ‘near zero’ until they detonate the weapon they’re creating.


‘This is a matter of life and death, but I can perform this miracle,’ the scientist insists, before later being heard proclaiming: ‘Our work here will ensure a peace mankind has never seen.’
‘Until somebody builds a bigger bomb,’ responds Benny Safdie as colleague and theoretical physicist Edward Teller, foreshadowing the destruction of the future.
‘You are the man who gave them the power to destroy themselves and the world is not prepared,’ cautions Branagh’s character, as a glimpse of Pugh as psychiatrist Jean Tatlock is offered.
Downey Jr. has been cast as Lewis Strauss, a founding commissioner of the United States Atomic Energy Commission who appears at the conclusion of the video, demanding on an answer for President Truman as a dramatic countdown from 10 concludes the footage.
Michael Angarano will play Robert Serber, while Josh Hartnett will play nuclear physicist Ernest Lawrence, with Oscar winners Rami Malek, Dane DeHaan, Dylan Arnold, David Krumholtz, Al Ehrenreich, and Matthew Modine all joining the cast.
Oppenheimer will be released in cinemas on July 21.
