“Star Wars” is shrinking at the box office. “The Rise of Skywalker” is nearing $1 billion worldwide, but it’s way behind the previous installments. “The Force Awakens” finished its theatrical run with $2 billion worldwide. That was an enormous hit. But the next chapter, “The Last Jedi,” ended up with $1.3 billion, a significant fall off. “Skywalker” shows “Star Wars” fatigue. It’s not quite at $1 billion, and it’s getting ready to say goodbye. Disney will keep it in movie theaters for a while but the big push is over.
