US President Donald Trump has announced plans to impose a 100% tariff on all foreign-made films imported into the United States. The move could significantly change the economic model of Hollywood, which relies heavily on international co-productions and box office revenue abroad.

Trump said the American film industry was being "stolen by other countries," comparing the situation to "stealing candy from a child." The statement echoes previous threats made by the president in May and has raised concerns among US studio executives.

It is not yet clear what legal mechanisms the administration plans to use to impose the tariffs. The White House has not provided official comments on the procedure for imposing the tariffs, creating additional uncertainty for the industry.

The uncertainty has already weighed on the market, with shares of major US film companies Paramount Skydance and Warner Bros Discovery down 2.1% and 1.3% respectively. Other major players, including Netflix and Comcast, have yet to comment on the potential impact.

Experts warn that modern filmmaking is largely international. Production processes, from filming to post-production and visual effects, are often spread across the US, Canada, the UK and Australia. International co-productions, particularly with partners in Asia and Europe, provide financing and access to global markets.

A broad application of the 100% tariff could affect thousands of US workers employed on overseas shoots, including visual effects artists and crews. Analysts note that additional costs associated with the duty will likely fall on consumers, which could affect the pricing policies of tickets and streaming platforms.
