Robert Downey Jr., known for his iconic role as Iron Man, delighted fans with a recent Instagram post featuring his Oppenheimer castmates. The highly anticipated biographical drama, directed by Christopher Nolan, centers around J. Robert Oppenheimer, portrayed by Cillian Murphy, and his leadership of the Manhattan Project during World War II.
In the Instagram photos, Downey can be seen on a rooftop alongside Emily Blunt, Cillian Murphy, and Matt Damon. The group appeared to be enjoying some pizza together during a break from their press tour. The first photo showed the actors with beaming smiles, while the second had a more serious tone. Interestingly, John Krasinski, Blunt’s husband, made an unexpected appearance in one of the shots, prompting Downey to humorously ponder whether it was a photobomb or a surprise cameo.
Fans were particularly delighted to see Cillian Murphy, known for his serious roles, wearing a broad smile in the group photo. Commenters jokingly speculated about the authenticity of the grin, with one suggesting it was photoshopped. Downey received praise for capturing a different side of Murphy, known for his intense performances in projects like Peaky Blinders and 28 Days Later.
In addition to sharing the group photos, Downey took the opportunity to showcase one of his press tour outfits, expressing gratitude to New York City for the positive reception of Oppenheimer. The actor, dressed in a pale yellow suit, patterned shirt, and gray combat boots, shared a photo on his Instagram Story with the caption, “Most def not posing… Amazing buzz for Oppenheimer. Thx NY! Paris here we come!”

Oppenheimer, based on the Pulitzer Prize-winning biography “American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer,” is set to premiere in theaters on July 21. Downey portrays Lewis Strauss, a former chairman of the United States Atomic Energy Commission and the main antagonist to the titular physicist.
Alongside Downey, Blunt, Murphy, and Damon, the star-studded cast includes Florence Pugh, Kenneth Branagh, David Krumholtz, and Josh Peck. Downey expressed his excitement for the upcoming film and promised a memorable U.S. premiere, leaving fans eagerly awaiting the release of Oppenheimer and the chance to witness the remarkable performances of this talented ensemble.
