Evil Dead II 1987

Though this really about uber-demon possession, those Necronomicon fiends don't just possess people. Hell, they even manipulate the woods themselves, when they conveniently need a path to disappear--very effective for trapping your humans. Like in Poltergeist, the trees and plants (and cabin objects, for that matter), are mere tools for the demons for terrorizing, and for Sam Raimi, the film's architect, to generate truly brilliant black comedic moments. Groovy!
