President Donald Trump announced plans on Sunday to implement a 100% tariff on foreign-made movies imported to the United States, accusing other nations of undermining the U.S. film industry with financial incentives that lure filmmakers away from Hollywood.

“Hollywood, and many other areas within the U.S.A., are being devastated. This is a concerted effort by other nations and, therefore, a national security threat,” Trump wrote on Truth Social. He labeled foreign films as “messaging and propaganda” that negatively affect the U.S. entertainment sector.

“I am authorizing the Department of Commerce and the United States Trade Representative to begin the process of instituting a 100% tariff on any and all movies coming into our country that are produced in foreign lands,” Trump added.

Speaking to reporters at the White House, Trump blamed other countries for “stealing” the U.S. film industry’s capabilities, and specifically called out California Gov. Gavin Newsom for the decline in Hollywood film production in recent years. A spokesperson for Newsom did not respond to inquiries on the matter.

“If they’re not willing to make a movie inside the United States, we should have a tariff when movies come in,” Trump asserted, adding that filmmakers would welcome the move.

The American film industry has faced several challenges in recent years, including labor strikes and the impact of the COVID-19 pandemic. California has seen a decline in physical production due to budget cuts and more appealing tax incentives in other regions. FilmLA, a nonprofit organization supporting film permits in Los Angeles, reported lower-than-average soundstage occupancy, with competing areas like the United Kingdom, Ontario, and U.S. states like New York and Georgia seeing significant production growth.

Despite overall production drops, the number of feature films produced in Los Angeles increased by 18.8% last year, although still below the five-year average.

Trump had earlier appointed actors Jon Voight, Mel Gibson, and Sylvester Stallone as special ambassadors to Hollywood, tasked with revitalizing the industry after what he described as a loss of business to foreign countries.

Voight’s manager, Steven Paul, confirmed that he and Voight intended to meet with Trump to present ideas for boosting U.S. film and television production, although it is unclear if that meeting has taken place.

The Motion Picture Association, which represents Hollywood’s leading studios, declined to comment. A recent report by the organization showed Hollywood maintaining a positive trade balance in all major global markets.

Meanwhile, China recently imposed new tariffs on Hollywood films, though reports suggest it may not have a significant financial impact due to declining box office returns from the region.

The proposed 100% tariff marks another chapter in Trump’s ongoing efforts to bolster American industries against foreign competition, including his previous push for similar tariffs on other goods imported into the United States.
