“In 2016, 736 films were released in US cinemas – more than double the number in 2000,” PwC notes. PwC predicts that box office revenue will continue to rely on a small number of big-budget studio “tentpole” and franchise movies, with the most successful accounting for a huge portion of overall receipts. It only takes one or two of these blockbusters to (say, Star Wars: The Last Jedi or, more recently, Black Panther) to keep revenue stable.
