On May 4, US President Trump announced through social media that he would impose tariffs of up to 100% on films produced overseas, which immediately attracted unanimous criticism from all walks of life in the United States and the mainstream media. The New York Times and other media outlets wrote that once the policy is implemented, it will lead to a sharp increase in film production costs and impact the global competitiveness of major US film companies. The Wall Street Journal reported that this policy directly caused the stock prices of major Hollywood film and television companies such as Netflix, Disney, Warner Bros. and Paramount to fall by more than 2%, triggering huge controversy and doubts in the industry. Industry experts generally believe that although Trump's move is under the banner of "protecting American films", it may actually hollow out the global collaborative foundation on which the US film industry relies for survival and further stifle employment. At present, several US industry associations are jointly writing to Congress, calling for a careful assessment of the economic and legal consequences of the policy.
