As an industry that makes movies and TV shows—in trade parlance: services, not products—Hollywood may have thought it was safe from President Donald Trump’s tariffs. Shares in Netflix, Disney, and other media properties started to slip, but the real uncertainty laid in a much different question: How the hell do you tariff movies? Tariffs, as Trump deploys them, are meant to make importing so financially unappealing that companies make their products in the US. A lot of the confusion over Trump’s proposed tariff is a result of the labyrinthine ways modern movies get made. More likely, studios would just make fewer films, or—as consumers have seen with tariffs on other goods—the price of hitting the cineplex would go up.
