This fine, puzzling documentary by Eric Walter consists largely of interviews with Daniel Lutz, who is, nowadays, a worker for the UPS, but who was, back in the 1970s, the oldest son of the Lutz family, who were at the heart of the ‘Amityville Horror’ paranormal case study/ media franchise. Walter gets to film Daniel playing guitar, riding around in hot rods, visiting a therapist and meeting up with various people who had a connection to the original case in some kind of quest to attain closure and peace.

The film lets everybody speak for themselves, with no editorial voice-over or evident bias, which is fair enough, though it does kind of assume that you’re familiar with the AH phenomenon, in which the Lutzes were supposed to have endured 28 days of supernatural assault after moving into a house that they picked up as a bargain after it had been the scene of a nasty mass murder (Daniel was 10 at the time). I, for one, could have done with a few more subtitles spelling out the facts where the facts are known. But this is a case where hard facts are hard to find. AH is a battleground between those who believe that it was all a hoax and those who believe the Lutzes’ account, with the waters further muddied by Jay Anson’s decidedly dodgy bestseller and the 1974 film, with its various sequels and remakes.

There are some great characters and strange ideas revealed along the way, and a visit to a psychic’s house (dozens of occult carvings, twin roosters crowing in cages, a piece of the ‘true cross’ revealed) that is weird comedy gold. But the main reason to watch My Amityville Horror is Daniel, clearly scarred by the dysfunctional home life that erupted into a media sensation. He fled home at 14 and is now estranged from his family, paranoid, intense and angry, and prone to making forceful statements that beg more questions than they answer. A brittle man in a macho shell, he recalls the subject of Errol Morris’s 2011 doc Tabloid, another film where the very idea of ‘truth’ becomes slippery and elusive. Did this stuff happen? Does Daniel need to believe it did? A film to argue over.
