The film earned over $700 million at the worldwide box office, making it the highest-grossing horror movie of all time.
The cast for the highly-anticipated sequel IT: Chapter Two has now grown with the additions of indie horror star James Ransone (Sinister) and actor Andy Bean (Power), according to Deadline.
The second part of IT is written by Gary Dauberman from the book by Stephen King, and will be directed once again by Andy Muschietti.
It clocked in just $9 million behind Deadpool for the second-highest opening for an R-rated movie.
