Looks like It is pretty much a certified blockbuster.

Horror blockbuster “It” has turned into a box office monster, crossing the $500 million milestone in worldwide grosses — making it officially the top horror film of all time.

Warner Bros. announced Thursday that “It” has eclipsed the 44-year record belonging to “The Exorcist” as the top grosser among horror films with $441 million. The studio noted that record for “The Exorcist” had been one of the longest-held records in cinema history.

“It” scored the biggest opening weekend ever for a horror film in more than 30 markets, including the U.K., Russia, Brazil, Mexico, and Australia. In 17 of those territories, including the U.K., Russia, and Australia, “It” has already become the top-grossing horror film of all time. The film has plenty of gas in the tank, too, as it has yet to open in Germany, Italy, and Japan.

That’s damned rock-solid for a R-rated horror film. Like the article notes, it’s surpassed The Exorcist and as noted, the film hasn’t opened yet in Germany, Italy and Japan - three countries where horror flicks traditionally do quite well.
