This is an interesting case of a movie being better than the book, and we need to give props to “The Exorcist” author William Peter Blatty. He was adamant that he be hired to write the screenplay for the movie based on his novel, and that paid off in a big way.
It’s hard to explain exactly how terrifying audiences found this movie when it first came out, or what a gigantic hit it was. “The Exorcist” made $441.3 million at the box office in 1973, which is equivalent to $2.7 billion in today’s money.
That’s roughly the same amount of money that the No. 1 box office movie of all time, “Avengers: Endgame,” made when it was released in 2019.
