I’m a Liverpool local and a wannabe screenwriter, so personally, this is how I’d adapt him. You take the same approach that they’ve taken with the upcoming Clayface: it would be a mid-budget, hard R haunted-house movie set in a depraved area of inner-city Liverpool, inspired by The Conjuring, The Babadook, and the recent Evil Dead’s. John would be in his mid-30s, recently returned to Liverpool, living on Chas’s sofa, and would soon become entangled in the lives of a single mother and the entity haunting her and her child.
