On July 21, Oppenheimer, the thirteenth feature film by Christopher Nolan, will be released in theaters, including in IMAX format. 

The film, based on the biography American Prometheus by Kai Bird and Martin J. Sherwin, covers the life of American physicist Robert Oppenheimer, known as the father of the atomic bomb, spanning a narrative arc of 45 years. 

How long is Christopher Nolan Oppenheimer?

Reports have revealed that the film’s runtime will be over three hours, making it the longest film in Christopher Nolan’s career, beating Interstellar’s 169 minutes. 

Matt Damon says, “It’s three hours. It’s fantastic. Cillian is phenomenal. He’s everything you would want him to be. I think it’s almost three hours. It goes so fast, it’s great.”

Oppenheimer, written and directed by the acclaimed filmmaker behind blockbusters such as The Dark Knight, Inception, Interstellar, and Tenet, is set to be a lengthy movie, which should not be a surprise to fans.

The film’s extended runtime promises to deliver an immersive and comprehensive experience of Oppenheimer’s life and work and the history of the atomic bomb. Christopher Nolan has a history of favoring extended runtimes for most of his previous works, except for Dunkirk, which was still an intense and tightly-edited film.
