The Seven-Per-Cent Solution

Dr. Watson (Robert Duvall), concerned that his friend Sherlock Holmes' (Nicol Williamson) use of cocaine has addled his brain, urges Holmes to travel to Vienna and seek the counsel of a certain Dr. Sigmund Freud (Alan Arkin). Among other things, Holmes has a wild theory that the upstanding intellectual Professor Moriarty (Laurence Olivier) is some kind of master criminal.
