1. Augustus Prew, who plays the lead Adam Ellis, said he was drawn to this film because he has a long history of being haunted himself.
2. The lights would go out on the Dear David set for no reason, for example while Augustus was in hair and makeup with nobody else around.
3. The production was filmed in a house that was supposed to be empty, but a few crew members found some people hiding in the attic of the house and had a jump-scare themselves.
