They Might Be Giants is also the title of a 1971 film written by James Goldman and directed by Anthony Harvey. The movie stars George C. Scott as Sherlock Holmes (sort of) and Joanne Woodward as Dr. Watson. The movie is something of a blend of Don Quixote, Don Juan DeMarco, The Fisher King and Sherlock Holmes: the plot deals with a delusional paranoid who believes himself to be the great fictional detective, and the psychiatrist who, despite her better judgment, falls under his spell and follows him around Manhattan.
