With a recent teaser, the makers of Christopher Nolan's Oppenheimer have revealed that the upcoming film is rated R for some nudity, sexuality and language. The film becomes the first R-rated feature directed by Nolan since his 2002 film Insomnia. 

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.

Oppenheimer is set to hit theatres on July 7.
