Drugs hook Sherlock Holmes in this 1976 Herbert Ross film that reveals the human side of the super sleuth, and throws in a real-life psychiatric legend for good measure. Under the influence of his "seven percent solution," the cocaine mixture he concocts to ease his mental anguish, Holmes goes a bit bonkers and makes a bloody nuisance of himself. Nicol Williamson brilliantly plays the vulnerable Holmes, a role that many critics believe should have won him an Oscar. Williamson receives strong support from Robert Duvall as Dr. Watson and Alan Arkin as Freud. The period atmosphere and costumes are first rate, as is Nicholas Meyer's screen adaptation of his own novel. The plot moves briskly along, and despite the focus on the heady stuff of psychiatry and criminology, includes plenty of good, old-fashioned physical derring-do, including a sword fight atop a moving train.
