Filmmaker Christopher Nolan explains why the Cillian Murphy-starrer Oppenheimer is his most successful film to date.

He also talked about the movie business. The filmmaker struck box office gold with Oppenheimer this year. Nolan is now looking back at the year and giving his take on the cinema landscape as of now.

“I’ve just made a three-hour film about Robert Oppenheimer, which is R-rated and half in black-and-white – and it made a billion dollars. Of course, I think films are doing great,” Nola said in an interview with Empire.

“The crazy thing is that it’s literally the most successful film I’ve ever made.”

He continued: “I’ve been doing this for 20 years and in the United Kingdom, it’s my highest-grossing film. So, I feel great about the state of the movie business based on my own experience. But also based on seeing other movies break out, seeing audiences come back.”

Oppenheimer is based on the life of Robert Oppenheimer, the American theoretical physicist who is called the 'father of the atomic bomb' and his role in the Manhattan Project during World War II. Oppenheimer has been credited as the director of the Los Alamos Laboratory, a place known for assembling bombs.

Cillian Murphy stars as the titular character, marking his debut as a lead in Nolan's films. He has earlier appeared in the director's Inception, Batman Begins, The Dark Knight, and Dunkirk, to name a few. Apart from Cilian, Oppenheimer also stars Florence Pugh, Robert Downey Jr, Gary Oldman, Rami Malek, and Kenneth Branagh, among others. 

Oppenheimer was released to huge critical and commercial acclaim, becoming the highest-grossing biopic ever with more than $950 million worldwide gross.
