The very first Footage Christopher Nolan’s Oppenheimer movie was shown exclusively in theaters prior to IMAX screenings of the new Avatar.

Just like the director’s previous film, Tenet, the trailer for “Oppenheimer” was shown exclusively in theaters in front of a major film release, in this case, in front of Avatar: The Way of Water’s IMAX screenings. So it is entirely possible as well that the footage will most likely not be released online or elsewhere.

“Oppenheimer” is based on the Pulitzer Prize-winning biography American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin. The upcoming biographical film is written and directed by Christopher Nolan and stars Cillian Murphy as J. Robert Oppenheimer, the American theoretical physicist who is credited often as the “father of the atomic bomb” for his role in the Manhattan Project, the research and development undertaking during World War II that produced the first nuclear weapons.

During a recent interview with Total Film magazine, the director mentioned that they had recreated the Trinity test, which is the first successful detonation of a nuclear weapon, without the use of CGI.

The film includes a star-studded cast which includes, Emily Blunt, Matt Damon, Robert Downey Jr., Florence Pugh, Rami Malek, Jack Quaid and Matthew Modine among many others.

Oppenheimer is set for release on July 21, 2023, by Universal Pictures.
