For the first time ever, the annual box office has hit $6 billion before the end of June, thanks to mega hits like "Black Panther," "Avengers: Infinity War," and "The Incredibles 2." As a comparison, in 2017, the domestic box office reached $5.64 billion by the end of June 30.

And if things keep at a steady pace through the rest of the year, 2018 can top 2016's record total of $11.3 billion.

The year started off fairly strong with holdover from the holiday movies, including "Star Wars: The Last Jedi," "The Greatest Showman," and "Jumanji: Welcome to the Jungle." Then in February, "Black Panther" wowed audiences and critics and hauled in $700 million domestically.

Also adding to the big numbers were expected franchise hits "Deadpool 2" and "Jurassic World: Fallen Kingdom" and some surprises like "A Quiet Place."
