‘Oppenheimer‘ is being directed by Christopher Nolan. If there’s one thing special about Nolan’s movies, is his attention to detail in each frame. Christopher Nolan uses very minimal CGI (Computer Generated Imagery) in his movies and keeps it as realistic as possible. The only time he ever had to use CGI was to put Mathew McConaughey in Space, in Interstellar(2014).
For the filming of Oppenheimer, Christopher Nolan recreated most of the scenes in their original locations. This is his first film which will not be distributed by Warner Bros. Oppenheimer is being distributed by Universal Pictures and is all set for a theatrical release on July 21, 2023.

Oppenheimer Filming Locations
In a feature video for the movie released by Universal Pictures, Christopher Nolan talks more about the filming process.
“I always try to use real locations as much as possible, with location shooting or sets, the more thing that can just be real, the better they’re going to feel to the audience”.
With the technology being so advanced that you can recreate any location within the confines of a green screen, Christopher Nolan is one of the few directors out there that keep it as real as possible.

“We built our Los Alamos at Ghost Ranch, New Mexico, which is along the same mountain range that Los Alamos proper sits on,” says production designer, Ruth De Jong. “This was very important and I based all of this on research, we built all of these buildings, 360. We wanted to feel like you’re right there.”
Cillian Murphy who plays the role of Robert J. Oppenheimer in the movie also talks about how it was filmed in different locations for the movie.
“There’s almost no studio work in this film, everything was location. We also shot in a huge amount of the real locations, we shot in Oppenheimer’s house in Los Alamos, we shot in Princeton.”

Most of the shootings took place in New Mexico. A few scenes were shot at Institue For Advanced Study, Princeton, New Jersey. Oppenheimer was primarily shot using IMAX 65MM and 65MM wide format, so it will be interesting to see how real these locations look on the big IMAX screens.
