Cillian Murphy leads in Oppenheimer trailer

Christopher Nolan's next film is about the making of the atomic bomb.

Cillian Murphy plays J Robert Oppenheimer, the man tasked with making the bomb a reality.

Emily Blunt plays his wife Katherine 'Kitty' Oppenheimer, Matt Damon plays General Leslie Groves Jr, and Robert Downey Jr plays Lewis Strauss.

The trailer shows the immense pressure Oppenheimer is under to make sure the US is the first to make the bomb.

General Groves wants clean results and requests to work on the project in a remote town away from prying eyes.

The film is based on the Pulitzer Prize-winning book American Prometheus: The Triumph and Tragedy of J Robert Oppenheimer.

The ensemble cast includes Florence Pugh, Benny Safdie, Michael Angarano, Josh Hartnett, Rami Malek, Kenneth Branagh, Dane DeHaan, Alden Ehrenreich, and Matthew Modine.

Fans are eagerly awaiting the film's release and expect it to be watched on the big screen.

Oppenheimer will be released in theaters worldwide on July 21, 2023.

It will be released on the same day as Greta Gerwig's Barbie.
