Stephen King's 'IT' becomes highest-grossing horror film of all time at US Box-Office

Pennywise the Clown has completely creeped out all the competition at the ticket windows.

The blockbuster adaptation of Stephen King's 1986 novel of the same name as pushed past The Exorcist to become the highest-grossing horror film on a domestic basis, reports Entertainment Weekly.

The Andres Muschietti directed movie has made $236.34 million domestically in mere 14 days. In contrast, The Exorcist had grossed $232.9 million domestically.

The Exorcist became the genre's highest grossing title of all time at the domestic box office, unadjusted for inflation.

But, The Exorcist is still the top-grossing horror film on an international basis, having netted $441.3 million globally to IT's $404.3 million.

This isn't the only record the movie has broken during its short tenure in theatres so far.

The picture's $123.4 million opening weekend registered the biggest September debut (a bar previously set by Hotel Transylvania 2's $48.5 million debut back in 2015), the largest opening for a horror release, and the second-best three-day frame for an R-rated movie.

The film is also the ninth highest-grossing R-rated release in history and the highest-grossing September release.

IT is directed by Andres Muschietti and stars Bill Skarsgard as Pennywise, along with a kid-heavy cast that includes Jaeden Lieberher, Jeremy Ray Taylor, Sophia Lillis, and Finn Wolfhard.

The movie follows a band of outcast teenagers as they battle a sinister force that's terrorizing their town.
