Donald Pleasence, Shelley Winters, Tammy Grimes, and Terry-Thomas star in the obscure British black comedy Arthur!! Arthur? Pleasence plays a henpecked, introverted little nebbish, unhappily wed to Winters. Escaping into fantasy, Pleasence conjures up an extroverted alter-ego, which eventually overtakes his "real" self. Newly emboldened, he murders his wife, cashes in her insurance policies, and runs off with Grimes. But she proves a bit too clever for both of Pleasence's personalities. ~ Hal Erickson, Rovi
