The Hitchcock festival continues! To prove their superiority by committing the perfect crime, precocious Brandon (John Dall) and nervous Philip (Farley Granger) strangle a college classmate, fold his body into a wooden chest, then hold a cocktail party around the corpse in Rope. Guests include the victim’s parents, girlfriend, and the very curious, equally intellectual publisher Rupert (James Stewart). Loosely based on the Leopold-Loew case, and edited to appear as if it was shot in a single take, Rope is an almost unbearable study in tension. At the Heights. THURS, 7:30 PM. $12. Then in The Man Who Knew Too Much, Hitchcock once said that the audience would have to know how to read music in order to appreciate the suspense in this film. Indeed, Bernard Herrmann’s score is pivotal to the nail-biting finale of this tale about a family of American tourists in Morocco who accidentally cross paths with international assassins. Que séra, séra. At the Trylon. FRI-SUN. $8.
