The first Paranormal Activity cost just $15,000. It went on to gross more than $107 million in the U.S. alone, making it one of the most profitable films of all time. That’s just one of the many facts packed into the latest episode of You Think You Know Movies, which heads deep into the ghost dimension for a look at the first Paranormal Activity.

The film’s stars, Katie Featherston and Micah Sloat, were each paid just $500 to star in the movie. (No wonder the budget was so low!) DreamWorks and Paramount Pictures initially paid $350,000 for the rights to the film and planned to simply remake it at a higher budget; director Oren Peli convinced them to do a test screening of the film which was so successful that it led to a full theatrical release. While Paranormal Activity went on to inspire several American sequels (the latest opens this Friday), it also spawned a Japanese sequel/remake, called Paranormal Activity 2: Tokyo Night.
