This thoroughly plotted film draws upon a wealth of influences, most specifically Rear Window, The ‘Burbs, The Conjuring, The Grudge, The Blair Witch Project, and The Evil Dead.
Brett and Drew Pierce are the sons of visual-effects artist Bart Pierce, who did uncredited work on Sam Raimi’s 1981 classic horror flick “The Evil Dead.”
For a horror-movie aficionado, The Wretched is a swirling bloody cocktail of nods to some of the genre’s most beloved titles, such as Invasion of the Body Snatchers, Rear Window and The Evil Dead .
The other horror elements in the film are derivative of classics: "unwitting unleashing of a demonic force in the forest" from The Evil Dead , "my next-door neighbour is a demon in disguise"from Friday Night , and "my neighbours have become pod people" from Invasion of the Body Snatchers.
And brothers/writers-directors Brett and Drew T. Pierce are the sons of Bart Pierce, who worked on special effects for Sam Raimi's The Evil Dead .
