《恐怖的研究 A Study in Terror》 是JamesHill导演的作品，发行于1965年（英国），由约翰·内威尔,唐纳德·休斯敦,约翰·弗拉瑟等主演的一部剧情片。
讲述了：When Watson reads from the newspaper there have been two similar murders near Whitechapel in a few days, Sherlock Holmes' sharp deductive is immediately stimulated to start its merciless method of elimination after observation of every apparently meaningless detail. He guesses right the victims must be street whores, and doesn't need long to work his way trough a pawn shop, an aristocratic family's stately home, a hospital and of course the potential suspects and (even unknowing) witnesses who are the cast of the gradually unraveled story of the murderer and his motive.
