The poster suggests that The Amityville Horror takes place in a real town called Amityville and involves something horrifying. It shows a man walking towards a big, old house in the woods holding a gun. This implies that the film will focus on a man trying to kill everyone in the isolated house. The tagline "Watch 'em and kill 'em" further hints that he has been watching the residents and is now going to kill them, possibly as a hired assassin. The overall dark tones and imagery aim to create an atmosphere of danger and suspense.
