In which the haunters become the haunted.

Five friends form a professional haunt company, staging elaborate Halloween tours in creepy locations. The opening of their latest attraction is not entirely successful, as most of the staff ends up deceased in gruesome fashion.

The police and civic authorities shut down subsequent investigations, but five years after the Halloween Holocaust, a documentary crew attempts to solve the mystery by tracking down and interviewing the lone survivor.

For fans of the found-footage genre, Hell House LLC doesn’t disappoint. Writer-director Stephen Cognetti peppers the premises with ghosts, demons, a Satanic cult, a big scary clown, and enough paranormal pageantry to make up for any quandaries about who’s supposed to be running the camera in this scene.

I cheerfully recommend the movie, and may go so far as to check out the two sequels it inspired.

Note to filmmakers on a budget: Behold the beauty of a found-footage film; the iPhone cinematography actually enhances the dreadful atmosphere, forcing the trembling viewer to strain for every grainy terror captured.

The very existence of sequels to Hell House LLC proves that someone made their money back—and that’s enough to keep the iPhones rolling.
