More than a thousand movie stars, writers, directors and other Hollywood professionals announced their “unequivocal opposition” to the proposed Paramount merger with Warner Bros. Discovery in an open letter published Monday.

A large swath of the movie industry, including Denis Villeneuve, Kristen Stewart, J.J. Abrams and Joaquin Phoenix came out forcefully against the $111 billion deal that would consolidate two legacy studios into one, arguing that it further reduce jobs and movies in an already downsized Hollywood.

“The result will be fewer opportunities for creators, fewer jobs across the production ecosystem, higher costs, and less choice for audiences in the United States and around the world,” reads the letter, posted on BlocktheMerger.com. “Alarmingly, this merger would reduce the number of major U.S. film studios to just four.”

In late February, David Ellison’s Paramount Skydance reached a deal to acquire Warner Bros. Discovery in one of the largest media mergers ever. The deal awaits a shareholder vote later this month and government regulatory approval. Paramount’s victory came after months of negotiations and a rival bid by Netflix that ultimately fell short.

Ellison, chief executive of Paramount Skydance, has pledged to keep Paramount and Warner Bros. as stand-alone movie studio operations, and vowed to release a combined 30 movies a year in theaters. Paramount has acknowledged the merger will also lead to significant cuts due to duplication.

In response to the open letter, Paramount issued a statement Monday arguing that the merger will give creators “more avenues for their work, not fewer.”

“This transaction uniquely brings together complementary strengths to create a company that can greenlight more projects, back bold ideas, support talent across multiple stages of their careers, and bring stories to audiences at a truly global scale,” the studio said.

But many in the film industry believe a merger will mean extensive job losses and a consolidation of power.

“We are deeply concerned by indications of support for this merger that prioritize the interests of a small group of powerful stakeholders over the broader public good,” read the letter. “The integrity, independence, and diversity of our industry would be grievously compromised.”
