Oppenheimer premiered at Le Grand Rex in Paris on July 11, 2023, and was theatrically released in the United States and the United Kingdom ten days later by Universal Pictures. Its concurrent release with Warner Bros.'s Barbie was the catalyst of the " Barbenheimer " phenomenon, encouraging audiences to see both films as a double feature. Oppenheimer grossed over US$977 million worldwide, becoming the third-highest-grossing film of 2023, the highest-grossing World War II-related film, the highest-grossing biographical film and the second-highest-grossing R-rated film.
