Aaron Sorkin’s adaptation of Harper Lee’s novel has passed the $40 million mark at the box office, with advance sales lifting the total to $55 million. There are still three British imports ahead of it: The Curious Incident of the Dog in the Night-Time ($68.3 million) and War Horse ($75 million), which Mockingbird will probably surpass, and Harry Potter and the Cursed Child ($118.7 million). – The Hollywood Reporter
