When we see, e.g., the haunted attic and desperate recourse to a priest (The Exorcist), the spectral sisters in the corridor (The Shining), the unhinged séance (Drag Me To Hell), the disembodied demonic footprints (Paranormal Activity), the comatose patient who seems only to be half asleep (Patrick), the body of a hypnotised man used as a portal by the dead (Two Evil Eyes), and the photographs exhibiting an eerie clairvoyant power (The Grudge, Shutter), Leigh and Whannell are not merely 'paying homage to as many films as they can', but throwing us apparent interpretative breadcrumbs that lead viewers - especially, but not exclusively, genre savvy viewers - in so many different and conflicting directions (how exactly do you get from The Exorcist to Patrick to Shutter?) that all this hyper-allusiveness conjures up its own kind of uncanny.
Whannell has come up with one slightly different idea which he lays on top of themes taken from everything from "The Exorcist" to "The Orphanage" to "Paranormal Activity" while director Wan cops visuals from "The Shining," "Poltergeist" "Drag Me to Hell" and even that 'ghost' from "Three Men and a Baby."
Anyone who thinks a haunted house movie by the creators of "Saw" would be a gory and grim affair clearly aren't aware of director James Wan and screenwriter Leigh Whannell's love for classic horror, specifically their admiration for two classic examples of the haunted house horror sub-genre at its best, "Poltergeist" and "The Shining."
References to The Shining, Rosemary’s Baby, The Others and more horror classics can also be found.
Fueled by smart sampling -- " Poltergeist ," " The Shining ," " Paranormal Activity ," " The Amityville Horror ," " The Exorcist " -- it feels like the Wan/Whannell brand of shivery fun may be heading toward something substantially terrifying.
(That soundtrack is a masterpiece of sonic manipulation, instrumental screeches, clangs, and dissonance that make this one of the best horror soundtracks since Kubrick tapped pre-existing work from the likes of Ligeti and Penderecki for The Shining.)
