The movie plot has a very strong resemblance to the Italian movie "La ragazza nella nebbia" (literally "the girl in the fog"). It looks like an American remake of it, but with a different ending.
Originally set to film in Minnesota, but due to finance delays production was re-located to Atlanta. Then more delays caused production to again re-locate to Los Angeles.
