Cameron Warns Netflix‑WBD Merger Could Undermine Theatrical Ecosystem and National CineMedia Ads

Filmmaker flags merger risk to cinema chain and ad ecosystem

Filmmaker James Cameron is warning that a proposed deal giving Netflix control of Warner Bros. Discovery’s studio could seriously weaken the theatrical ecosystem that companies such as National CineMedia depend on. In a letter to Senator Mike Lee obtained by CNBC, Cameron says the combination of two major studios and streaming services would reduce releases, shrink theatrical windows and drive job losses across Hollywood, a scenario that threatens box office attendance and the pre‑show advertising inventory cinemas sell to marketers.

A warning for cinema advertising and exhibition

The proposed transaction raises particular concerns for National CineMedia, which operates pre‑show advertising in thousands of U.S. movie theaters and relies on a steady flow of theatrical releases to deliver mass, appointment‑based audiences to advertisers. If consolidation leads to fewer high‑profile theatrical releases or shifts more titles to streaming day‑and‑date, cinemas could see lower attendance and shorter or less predictable runs, reducing the reach and frequency that underpin cinema ad pricing and campaign effectiveness.

National CineMedia’s business model also depends on the theatrical release calendar being broad and stable. Large studios drive promotional windows that fill auditoriums for weeks; if combined studio strategies prioritize streaming premieres or limit theatrical distribution, ad load and audience composition in the crucial evening and weekend slots could change materially. That in turn affects the agency and brand demand for targeted cinema spots that NCM sells, and may force exhibitors and their ad partners to renegotiate inventory planning and measurement metrics.

The company also faces indirect risks from industry job losses and supply‑chain contraction that Cameron cites. Fewer productions and reduced theatrical support can weaken local exhibition markets and ancillary services tied to film promotion and release events, altering attendance patterns in key metropolitan areas where NCM derives a large share of impressions.

Industry and regulatory backdrop

Cameron’s intervention follows an early‑February Senate subcommittee hearing on competition where Netflix co‑CEO Ted Sarandos and Warner Bros. Discovery executive Bruce Campbell testify. Lawmakers including Lee say they are receiving outreach from actors and directors and are weighing further oversight.

Netflix responds by citing written testimony and Sarandos’ remarks, saying the deal would increase U.S. production investment and that a stronger combined balance sheet supports more, not fewer, films. Regulators and antitrust lawmakers could still block or condition a transaction if they conclude it would harm theatrical distribution and downstream businesses such as cinema advertising.
