U.S. President Donald Trump on Sunday announced a 100% tariff on movies produced outside the country, saying the American movie industry was dying a "very fast death" due to the incentives that other countries were offering to lure filmmakers.

Donald Trump has claimed that a huge "national security threat" is facing the movie industry - and he intends to take action.
