Rebecca Rubin Film and Media Reporter “Fast X,” the 10th installment in Universal’s high-octane franchise, powered to $320 million worldwide, including an uninspired $67.5 million in its domestic debut. It secured the second-biggest global opening weekend of the year following another Universal title, “The Super Mario Bros. Movie” ($377 million). Even though “Fast X” arrived on the higher end of projections, the action-adventure saga has been experiencing diminishing returns in North America. In terms of opening weekend ticket sales, the 10th chapter landed behind the latest entry, 2021’s “F9: The Fast Saga,” which kicked off to $70 million. And that was at a time when COVID era restrictions meant only 80% of theaters were open and attendance hadn’t yet rebounded. Pre-pandemic “Fast” installments were far bigger in their starts, including 2017’s “The Fate of the Furious” ($98 million debut), 2015’s “Furious 7” (a series-high $148 million debut) and 2013’s “Fast and Furious 6” ($97 million debut).
