The US remains a major film production hub globally despite challenges, according to movie industry research firm ProdPro.
Its most recent annual report shows the country saw $14.54bn (£10.94bn) of production spending last year. Although that was down by 26% since 2022.
And NPR Radio film critic Eric Deggans warned that the tariffs, should they be introduced, could further harm the industry.
Other countries may respond by placing tariffs on American films, he told the BBC, making it "harder for these films to make profits overseas".
"It may create a situation where the tariffs in America are causing more harm than good," he added.
The Motion Picture Association, which represents the five major US film studios, declined to comment when contacted by the BBC.
Countries that have attracted an increase in spending since 2022 include Australia, New Zealand, Canada and the UK, according to ProdPro.
Following Trump's remarks, Australia's home affairs minister Tony Burke said: "Nobody should be under any doubt that we will be standing up unequivocally for the rights of the Australian screen industry."
Industry body Screen Producers Australia said that while there were "many unknowns" about the plan, there was "no doubt it will send shock waves worldwide".
New Zealand's Prime Minister Christopher Luxon also said his government was awaiting further details of the proposed tariffs.
"But we'll be obviously a great advocate, great champion of that sector and that industry," he told a news conference.
