Several Hollywood industry and labor organizations wrote to President Trump on Monday asking for tax breaks that they said would help bring more film and television production back to the United States.

Their letter was sent in response to Mr. Trump’s declaration on Truth Social this month that he would put a 100 percent tariff on films made outside the United States. It was signed by the Motion Picture Association, which represents the major Hollywood studios; the main writers’ and actors’ guilds; and the actors Jon Voight and Sylvester Stallone, two of Mr. Trump’s chosen Hollywood advisers.

“Returning more production to the United States will require a national approach and broad-based policy solutions,” the letter said.
