Rope marks the beginning of the Alfred Hitchcock and James Stewart partnership, which later produced films like "Rear Window," "The Man Who Knew Too Much," and "Vertigo." Being their initial project, and also an experimental effort for Hitchcock, it doesn't quite measure up to its successors. The film was created with a theatrical feel, primarily confined to one room and featuring a small cast, and the way it was achieved remains fascinating even now. It was filmed in approximately a dozen takes, and camera shifts are only noticeable when the lens focuses on someone’s back before pivoting to another viewpoint—that's how you can tell where cuts were made. John Dall delivers a noteworthy performance as Brandon Shaw, the more callous of the killers. His character is remarkably detached, showing no remorse for the violent murder he has carried out. James Stewart, while always pleasant to watch, seemed slightly awkward in his role as Rupert Cadell, an intellectual publisher. I've always admired Stewart’s abilities, but he seems a little uneasy with his part at times. The film’s suspense is also lessened by the initial scene depicting the murder itself. With David Kentley already placed inside the wooden chest, the audience knows from the very beginning that he’s dead and what has transpired. If Hitchcock had left out the actual killing, viewers would likely be questioning whether a body was truly in the chest, if the crime actually occurred, and what else might be happening. The misleading clues within the film would have only heightened the mystery. As it stands, we are informed from the outset who is deceased and who committed the act. Nevertheless, it’s an acceptable movie and still worthy of viewing.
