Matthew William Chizever showed his range of talents this past year in roles in plays as varied as My Fair Lady and Venus in Fur, but the multiple personality disorder that was The Turn of the Screw was a veritable master class in classic archetypes — five parts so distinct from one another in make, model, and year that it's hard to believe they were driven by the same man. For the part of Uncle, a London bachelor, he oozed sexual tension and casual seduction toward his skilled castmate Katherine Amadeo. He soon changed everything, while seemingly changing nothing, to transform into an elderly female housemaid who knows more than she lets on. Later, he assumed the form of a troubled 10-year-old boy. From stooping to kneeling, from British accents to Irish ones, Chizever subtly transitioned through this eerie ghost story like an implacable shape-shifting specter, haunting the floorboards with the many voices in his head. He even created 90 percent of the show's atmospheric sound effects, which were critical to its success.
