While the Marvel movies and the Mission: Impossible franchise have always done well in both places, Star Wars has never seen the success in China that the studio would like to see.
Hollywood films have been relying on international box office success, specifically that of China, more and more in recent years.
By comparison, films that struggle here, like Terminator: Genisys have made all their money back and then some when released in China.
However, not every film that a blockbuster here is nearly as successful overseas.
