Oscar-winner Rami Malek, ‘Black Widow’ star Florence Pugh and actor-filmmaker Benny Safdie have joined the team of ace filmmaker Christopher Nolan’s directorial project ‘Oppenheimer’.

The three actors join previously announced cast members Cillian Murphy, Emily Blunt, Robert Downey Jr. and Matt Damon in the film, PTI reported.

The Universal Pictures project is a biopic of J Robert Oppenheimer, the theoretical physicist remembered as one of the fathers of the atom bomb.

Murphy is set to star as J Robert Oppenheimer and Emily Blunt as his wife Katherine.

Pugh will essay the role of Jean Tatlock, a member of the Communist Party of the United States who has an off-and-on affair with Oppenheimer and was the cause of major security concerns for government officials.

Safdie will play Edward Teller, the Hungarian physicist who is known as the father of the hydrogen bomb and a member of the Manhattan Project, the US research initiative that developed the first atomic bomb.

Malek will also feature in the movie as a scientist.
