The film stars some of the most famous faces in Hollywood, including Peaky Blinders’ Cillian Murphy, 46, as J. Robert Oppenheimer and Emily as his wife, biologist and botanist Katherine “Kitty” Oppenheimer.

Little Women star Florence Pugh, 27, plays psychiatrist Jean Tatlock.

Nolan said, “It’s an intense experience because it’s an intense story. I recently showed it to a filmmaker who said it’s kind of a horror movie. I don’t disagree.’

The director even admitted that he was “relieved to be done” with the project because of the emotional toll it took.

“When I started to finish the movie, I started to feel this color that isn’t in my other movies, just darkness. It’s there. The film fights against that,” he said.

“I don’t really care about the size of the part, but deep down, secretly, I was desperate for him to star.”
