Oppenheimer had its world premiere at Le Grand Rex in Paris on July 11, 2023, followed by the British premiere at Odeon Luxe Leicester Square in London on July 13, and the American premiere at AMC Lincoln Square 13 in New York City on July 17. Both the London and the New York premieres were affected by the SAG-AFTRA strike, as some actors left the London premiere early, and Universal Pictures canceled the red carpet event for the New York premiere. SAG-AFTRA President Fran Drescher later claimed the studios "duped" the guild into accepting a twelve-day-extension for negotiations to continue promoting summer films like Oppenheimer. Oppenheimer was released theatrically on July 21, 2023, by Universal Pictures. In addition to standard digital cinemas, it was also released in various film formats including IMAX 70 mm (30 prints), standard 70 mm (113 prints) and 35 mm (around 80 prints).
