As of Friday, the movie will also become the top-grossing R-rated thriller of the past decade, the studio said.
"Paranormal Activity" began its theatrical life with midnight-only screenings in 12 college towns across the United States and quickly developed into a nationwide hit, with fans visiting the ParanormalMovie.com Web site and demanding the film be brought to their city.
After more than 1 million such requests, Paramount said it expanded the film nationally where it has been playing to packed theaters ever since.
"What is truly amazing about 'Paranormal Activity' is the depth of commitment from fans who demanded to see it," Paramount Pictures Chairman and Chief Executive Officer Brad Grey said in a statement. "Adam Goodman, our head of production, believed in the film and championed it from the very first screening. This box-office milestone is also a testament to Oren Peli's considerable talents as a filmmaker. All of us at Paramount are proud to have been involved with his revolutionary project."
