Hollywood's largest performers' union formally declared opposition to the proposed combination of Paramount and Warner Bros., joining regulators and other labour organisations in scrutinising the $111 billion deal. The union's national board voted on Saturday to resist the merger, aligning with efforts by twelve state attorneys general who have filed legal challenges to block the transaction.

SAG-AFTRA demands binding commitments to maintain or increase domestic film and television production before the deal proceeds, rather than accepting corporate assurances alone. The union's leadership argues that workers cannot depend on promises, emphasising that the companies possess the ability to guarantee continued American production. This represents the third major entertainment union to publicly oppose the merger, following vocal resistance from the Writers Guild of America and the Teamsters, whilst the CEO has previously pledged the studios would collectively produce at least thirty films annually.
