(L-R) Actor Micah Sloat, actress Katie Featherston and writer/director Oren Peli from the film 'Paranormal Activity' pose for a portrait at the Miners Club during the 2008 Slamdance Film Festival on January 18, 2008 in Park City, Utah.
"Paranormal Activity" has just surpassed "The Blair Witch Project" to become the most profitable movie ever.
The box office hit was made for less than $15,000 and as of Wednesday has grossed a whopping $65.1 million, TheWrap.com reported.
The movie's box office success has reaped a staggering 414,233 percent return on its initial investment.
"Paranormal" has gradually expanded from 12 to 33 to 160 to 760 to this weekend's 1,945 theaters – a move that some criticized – but one that Executive VP of Distribution for Paramount, Don Harris, credits as a key to the horror film's success.
"Everybody else thought we should be going faster than we were," he told TheWrap. "But I thought we were doing a pretty good job of seeding the ground as we went. I don't know that we would have done a lot more last weekend if we would have added a bunch of runs then."
The studio has reportedly spent less than $10 million to market the movie.
