My TiVo DVR memory has been swallowed almost totally by this TCM month-long presentation of the films of Alfred Hitchcock, a ridiculously generous overview that continues every Wednesday and Friday night all month. Truly, almost every film contains enough ingenuity and artistry to justify diving into it all over again – and if any of these films is new to you, please take full advantage of the opportunity. The movie that opens tonight’s tribute, for example, is 1948’s Rope (pictured), the director’s first full-color film, and one for which he set himself a fascinating, restrictive method of filming: Rope, about the execution and investigation of a cold-blooded “random” murder, would be performed by its actors in uninterrupted 10-minute takes (the length of a reel of film), then spliced together at carefully constructed, seemingly seamless edit points to make the action seem like a real-time, unbroken narrative. Take that, Birdman! That was almost 70 years ago – and it’s only the first of tonight’s Hitchcock movies shown until dawn tomorrow. Among the others: 1950’s Stage Fright (9:30 p.m. ET), and 1954’s classic Dial M for Murder (3:30 a.m. ET).
