Christopher Nolan Says Some ‘Oppenheimer’ Viewers Walk Out ‘Devastated’ and ‘They Can’t Speak’: ‘It’s Kind of a Horror Movie’

Christopher Nolan has a warning for anyone purchasing Oppenheimer tickets: The film might emotionally destroy you. Speaking to Wired magazine in a new interview, Nolan said that some early Oppenheimer viewers have had a visceral reaction to the film, which follows theoretical physicist J. Robert Oppenheimer (Cillian Murphy) as he creates the atomic bomb to end World War II.

Some people leave the movie absolutely devastated, Nolan said about early screenings. They cant speak. I mean, theres an element of fear thats there in the history and there in the underpinnings. But the love of the characters, the love of the relationships, is as strong as Ive ever done.

Nolan later added, It is an intense experience, because its an intense story. I showed it to a filmmaker recently who said its kind of a horror movie. I dont disagree.

Oppenheimers story is all impossible questions, Nolan added. Impossible ethical dilemmas, paradox. There are no easy answers in his story. There are just difficult questions, and thats what makes the story so compelling. I think we were able to find a lot of things to be optimistic about in the film, genuinely, but theres this sort of overriding bigger question that hangs over it. It felt essential that there be questions at the end that you leave rattling in peoples brains, and prompting discussion.

One outspoken fan of Oppenheimer ahead of the films July theatrical release is historian Kai Bird, who co-wrote the 2005 biography American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer with Martin J. Sherwin. Nolan adapted the book into Oppenheimer.

I am, at the moment, stunned and emotionally recovering from having seen it, Bird said during a recent conversation. I think it is going to be a stunning artistic achievement, and I have hopes it will actually stimulate a national, even global conversation about the issues that Oppenheimer was desperate to speak out about about how to live in the atomic age, how to live with the bomb and about McCarthyism what it means to be a patriot, and what is the role for a scientist in a society drenched with technology and science, to speak out about public issues.

Starring opposite Murphy in the drama are Emily Blunt, Matt Damon, Robert Downey Jr., Florence Pugh and more. The film is Nolans first R-rated release since 2002s Insomnia.

Oppenheimer opens in theaters nationwide July 21 from Universal Pictures.
