The house used to shoot interior scenes is the same house used for interiors in 1989's "Amityville: The Evil Escapes".
The poster features the 'Phantom Manor' attraction from Disneyland Paris with just a couple minor tweaks. This house is not the one used in the movie.
Amanda Barton, who wrote and acted in this film was part of the wardrobe crew for "Exorcism: The Possession of Gail Bowers" - which features the house used for the 2005 "The Amityville Horror" remake on the promos for that movie. Also, the house on the cover for "Amityville Terror" was not used in the movie, just as the house on the promotional items for "Exorcism: The Possession Of Gail Bowers" was not used in that movie, either.
Klaudia Kaye's debut as an actress and she also produced the film.
