This week marks the release of Oppenheimer, a film directed by Christopher Nolan and starring Cillian Murphy as J Robert Oppenheimer, the father of the atomic bomb. Nolan is known for his realistic approach to filmmaking and has once again demonstrated his skills by using practical effects to depict the intensity of the nuclear explosion, rather than relying on CGI. 
Some have even speculated that Nolan may have used a real atomic bomb for the Trinity Test sequence. Recently, in an interview, when asked about these rumours, Nolan took the opportunity to address them and clarify the truth.
In an interview with a leading US entertainment news portal, Nolan said, "It’s flattering that people would think I would be capable of something as extreme as that on the one hand, but it’s also a little bit scary."
Christopher Nolan is keeping quiet about how he captured the nuclear explosion in Oppenheimer, in order to maintain the mystery and keep the audience guessing. Despite this, the director has reassured fans that there is no use of CGI in the movie.
He said, "CG inherently is quite comfortable to look at. It's safe, anodyne. And what I said to Andrew on Oppenheimer is, 'This can't be safe. It can't be comfortable to look at it. It has to have bite. It’s got to be beautiful and threatening in equal measure'."
The upcoming movie Oppenheimer by Christopher Nolan takes inspiration from the book American Prometheus, co-authored by Kai Bird and Martin J. Sherwin. It delves into the life of J Robert Oppenheimer and his role in developing the atomic bomb during World War 2, which ultimately led to the devastating destruction of Hiroshima and Nagasaki in Japan. The film also stars Robert Downey Jr, Matt Damon, Florence Pugh, and Emily Blunt.
