More than a thousand of Hollywood’s most prominent writers, directors and actors signed an open letter Monday voicing their opposition to the proposed merger of Paramount and Warner Bros. Discovery. The letter reads in part, “The integrity, independence, and diversity of our industry would be grievously compromised. Competition is essential for a healthy economy and a healthy democracy. So is thoughtful regulation and enforcement.” Paramount Skydance announced its intended $111 billion acquisition of Warner Bros. Discovery earlier this year, after Netflix dropped its bid. Paramount’s offer still requires regulatory approval in the U.S. and Europe. If completed, it would create the largest media conglomerate in U.S. history, spanning news, sports, movies, video games, theme parks and more — all controlled by Paramount Chairman David Ellison, a vocal supporter of President Trump.
