Christopher Nolan Confirms Oppenheimer is His Longest Movie Yet

By Adam Barnhardt

When Oppenheimer hits theaters this summer, it will be the longest film on Christopher Nolan's resume. In a recent interview with Total Film magazine, the filmmaker revealed the biopic will clock in with a runtime larger than that of Interstellar. Though it appears a final cut isn't ready just quite yet, Nolan's comments would seem to suggest Oppenheimer will be longer than two hours and 49 minutes, the final runtime of Interstellar.

"It's slightly longer than the longest we've done," Nolan told the magazine. "It's kissing three hours."

What is Oppenheimer about? 

The film follows the life of J. Robert Oppenheimer, the director of the Los Alamos Laboratory during the time of the Manhattan. Project, the government directive that built the United States its first nuclear weapon. Cillian Murphy steps into the role of Oppenheimer, something the actor's been after since he and Nolan first worked together on Batman Begins.

"He's so understated and self-deprecating and, in his very English manner, just said, 'Listen, I've written this script, it's about Oppenheimer. I'd like you to be my Oppenheimer.' It was a great day," Murphy told The Associated Press. "I have always said publicly and privately, to Chris, that if I'm available and you want me to be in a movie, I'm there. I don't really care about the size of the part. But deep down, secretly, I was desperate to play a lead for him."
