(at around 4 mins) According to an interview with Jorge Diaz, when he did his scene where his character Hector performs a stunt on a laundry basket, he was supposed to glide down the stairs fast. However, the basket (supported with wire to pull it down the stairs, along with a skateboard underneath the basket, its wheels removed) often got stuck between in the steps. Finally on the last take, a member of the crew yanked the cable, which brought down the basket and actor to the bottom of the stairs; eliciting Diaz's genuine reaction. This last take was used in the final film.
The first and only Paranormal Activity film to feature the Paramount opening logo and title card.
Due to the longer production, filming didn't wrap until late July 2013 resulting in the original release date of October 25, 2013 being pushed to January 3, 2014. Making it the only Paranormal Activity film to not be released in the month of October.
First film in the franchise not to feature any "nights".
Takes place six years after the events of Actividad paranormal (2007) and immediately after the events of Actividad paranormal 4 (2012).
