On Tuesday “Barbie” topped $537 million, making it the highest-grossing domestic movie in Warner Bros. Discovery’s 100-year history. The flick surpassed Christopher Nolan’s “The Dark Knight,” which generated $536 million in 2008, for the title. “Barbie” has collected more than $1.2 billion at the global box office since its July 21 release. It is the first billion-dollar film for the newly minted Warner Bros. Discovery, the result of the Warner Media and Discover merger in 2022, and only the second movie released in 2023 to do so. Universal’s “The Super Mario Bros. Movie” has topped $1.3 billion since its April debut.
