A significant wave of opposition has emerged from Hollywood regarding the proposed merger between Paramount and Warner Bros. Over 1,000 prominent figures, including Florence Pugh, Pedro Pascal, Mark Ruffalo, and Emma Thompson, have signed an open letter condemning the deal. Critics argue that the merger poses a threat to the industry and could concentrate market power excessively. The American theater community, alongside actors and filmmakers, is rallying to block the acquisition, with major voices like Kristen Stewart and Joaquin Phoenix joining the outcry. The UK competition watchdog plans to launch a formal probe into the deal, which is expected to face further scrutiny from industry leaders and audiences alike. As pressure mounts, theater operators emphasize the potential harm to the theatrical landscape and advocate for longer release windows instead.
