Directed by Christopher Nolan, ‘Oppenheimer’ tells the story of Julius Robert Oppenheimer, a key figure in the atomic bomb and nuclear weapons, who was head of the Los Alamos Laboratory in World War II and then the head of the secret Manhattan Project that developed the first nuclear weapons. The highly anticipated film also comes to the fore with the discussions of whether visual effects were used or not.
The film’s director, Nolan, has always said that he is generally not keen on using computer-based imagery in his films, and that effects are just to make everything feel perfect He said it could be used when needed.
The director has also made statements in this direction about the Oppenheimer movie; He stated that no CGI was used in the movie. Moreover, World War II and atomic bomb although the subject. These statements were perceived as having no visual effects in the film, causing controversy.
Shortly before the movie’s release, the images brought up these explanations again;
But of course the truth is a little different. Because although Nolan’s films do not use CGI, VFX is used.
Actually, there are differences between CGI and VFX.
To clear this confusion Differences between CGI and VFX Let’s take a look;
- CGI; Computer-generated imagery is a technique that we can translate into Turkish as a computer-based image. In this technique, everything you see on the screen is computer generated. Think of it like the ‘Gollum’ character from The Lord of the Rings. So totally created with the help of computers characters or designs.
- VFX, on the other hand, is effects such as fire and explosion in the production. The images taken in front of the green screens that we often encounter, by mounting other scenes or models on it. It is also possible to show them together.
In short, we can say that the difference is that everything is computer-based in CGI, and the real image is supported with effects in VFX.

Now that we understand the CGI and VFX differences, let’s get back to the movie.
As we mentioned at the beginning, it seems impossible not to use visual effects in a movie about the atomic bomb. One atomic explosion, How can it be shown without using effects?
This is where the difference between CGI and VFX comes into play. CGI-based visual effects may not have been used in the movie. After all, it’s like ‘Gollum’ in every movie new characters or designs There is no need to create.
However, that doesn’t mean they don’t use visual effects, meaning they don’t make use of VFX. Although no computer-based visual effects are included, using VFX technology scene enhancements of course its possible. Nolan also said that they actually shot everything, even if there were effects in the movie; he simply means that they are using effects to ‘optimize’.
