14 – The most profitable film ever is Paranormal Activity.
Paranormal Activity, the science fiction horror film (and ensuing series) was written, directed, photographed, and edited by one man, Oren Peli. Still today, this simple yet jittery movie remains the most profitable movie ever made.
The movie that revolves around a couple who feel they’re being haunted by supernatural forces was fully produced at just $15,000 yet earned a mind-blowing $193 million. With the resulting three sequels, the Paranormal Activity franchise has spent a total of $13 million on production, but have collectively earned over $570 million.
