It also has added Michael Caine, Dunkirk‘s Kenneth Branagh, Dimple Kapadia, Aaron Taylor-Johnson and Clémence Poésy to and ensemble cast topped by John David Washington along with Robert Pattinson and Elizabeth Debicki.

The film, Nolan’s first feature since 2017’s Oscar-nominated Dunkirk, is being described as an action epic evolving around the world of international espionage. He wrote the original screenplay and shooting spanning seven countries is now underway. The studio has already set a July 17, 2020 release date for it.

The score is being composed by Black Panther Oscar winner Ludwig Göransson.
