Here are seven major questions left unanswered on Trump’s proposal: Trump only said he was “authorizing” the U.S. Trade Representative and the Commerce Department to impose a 100% tariff on foreign films. He didn’t say he would do it. With previous tariff threats, Trump has sometimes made good and sometimes backed off in the face of pressure.

President Trump’s announcement that he intends to place big tariffs on films that are produced abroad has one big problem: It is likely against the law. That’s because Congress nearly 40 years ago passed a law explicitly barring the president from regulating in any way the import or export of things like movies,

It's not just hard goods like cars and smartphones. Tariffs could become a factor in the costs of making and watching movies.
