Nightmare Reunion was filmed over a 4 year period due to many obstacles. Director Shawn Allen didn't want it released until he felt it was worthy.
Nichole Shea had never acted before, but filled in as a favor to the director when an actress fell through a week before shooting.
Director Shawn Allen took the role of John when he couldn't find an actor that was available.
The opening scene was suppose to take place during the 90's when grunge was popular. It was a surprise to the producers when all the young actors showed up in plaid. They thought maybe a couple, but not the whole bunch.
This is the third time Shawn Allen and Ian Lyons collaborated on writing a film together. They co-wrote Madman Chronicles and the Rental.
