Director Christopher Nolan has revealed in a new interview that he created the look of a nuclear explosion in his upcoming film “Oppenheimer” without the use of computer-generated imagery (CGI).

In an interview with Total Film, Nolan explained the challenges of recreating the Trinity test, the first nuclear bomb explosion, using practical effects.

He stated, “I think recreating the Trinity test without the use of computer graphics was a huge challenge to take on.”

Nolan enlisted the help of Andrew Jackson, his visual effects supervisor, early on in the process to help him achieve this goal.

Jackson worked on representing quantum dynamics and quantum physics in the film, as well as recreating Los Alamos, New Mexico on a mesa in the state, in extraordinary weather conditions. Nolan said, “there were huge practical challenges” in achieving this.

This is not the first time Nolan has chosen to use practical effects over CGI in his films.

In “Inception,” he used a rotating hallway to film the big fight scene instead of relying on computer-generated imagery.

Nolan called “Oppenheimer” a challenging project, stating “it’s one of the most challenging projects I’ve ever taken on in terms of the scale of it, and in terms of encountering the breadth of Oppenheimer’s story.”

He added, “There were big, logistical challenges, big practical challenges. But I had an extraordinary crew, and they really stepped up.”

Despite the challenges, Nolan is pleased with the results of his team’s efforts.

He said, “It will be a while before we’re finished. But certainly, as I watch the results come in, and as I’m putting the film together, I’m thrilled with what my team has been able to achieve.”

“Oppenheimer” tells the story of J. Robert Oppenheimer, the physicist known as the “father of the atomic bomb.”

The film stars Cillian Murphy as Oppenheimer, and it is not yet known when it will be released.

J. Robert Oppenheimer was an American theoretical physicist and professor of physics at the University of California, Berkeley.

He is best known for leading the Manhattan Project, the program that developed the first nuclear weapons during World War II.

Oppenheimer is often referred to as the “father of the atomic bomb” for his role in the project.

Oppenheimer’s story is a complex one, and it will be interesting to see how Christopher Nolan chooses to portray it on the big screen.

The use of practical effects in recreating the Trinity test and Los Alamos, New Mexico, is a bold move, and it will be fascinating to see how it turns out.

It is also worth noting that Christopher Nolan is known for his visually striking and ambitious films, and his decision to use practical effects over CGI in “Oppenheimer” adds to the anticipation for the film.

The use of practical effects is a refreshing change in an era where CGI is often overused, and it will be exciting to see how it adds to the overall look and feel of the film.
