As Christopher Nolan’s much-hyped film Oppenheimer is all set to hit the theatres on July 21, the makers released a 5-minute preview of the film on Friday. 

The preview provides a closer look at Robert Downey Jr.’s character and features various scenes from the film that are showcased as a culmination of black-white footage. Unlike the earlier released trailers, the preview weaved as more conversational.

The film stars Cillian Murphy as J Robert Oppenheimer, the American theoretical physicist who is called the ‘father of the atomic bomb’ and his role in the Manhattan Project during World War II. Oppenheimer has been credited as the director of the Los Alamos Laboratory, a place known for assembling bombs.

Cillian Murphy stars in the titular character, marking his debut as a lead in Nolan’s films. He has earlier appeared in the director’s Inception, Batman Begins, The Dark Knight, and Dunkirk, to name a few. Apart from Cilian, Oppenheimer also stars Florence Pugh, Robert Downey Jr, Gary Oldman, Rami Malek, and Kenneth Branagh, among others
