Over 1,000 filmmakers, actors, and entertainment industry professionals have signed an open letter opposing the proposed merger between Paramount Skydance and Warner Bros. Discovery, a deal valued at roughly $110 billion.

The letter warns that combining two of Hollywood’s largest studios would reduce competition in the film and television industry, potentially shrinking opportunities for creators while increasing pressure on jobs across production and related sectors. It also argues that consolidation could lead to fewer films being produced and a narrower range of stories reaching audiences.

Among the signatories are actors Joaquin Phoenix and Mark Ruffalo, along with other filmmakers and entertainment professionals who argue the merger would further concentrate control of major content pipelines.

The proposed deal would combine major studio operations and streaming platforms, including Paramount+ and HBO Max, into a unified service, creating one of the largest entertainment distributors in the industry.

Neither Paramount Skydance nor Warner Bros. Discovery immediately responded to requests for comment regarding the letter.

Industry analysts say the petition reflects growing concern within Hollywood over continued consolidation, though they note it is unlikely to derail the transaction on its own. Regulatory review is expected in both the United States and Europe, where officials will assess potential impacts on competition and consumers.

Rob Bonta has confirmed that California regulators are also examining the deal and have pledged a thorough review process.
