They Might Be Giants is a 1971 film based on the play of the same name (both written by James Goldman) starring George C. Scott and Joanne Woodward. Occasionally cited mistakenly as a Broadway play, it never in fact opened in the USA. It was directed in London by Joan Littlewood in 1961, but Goldman believed he "never got the play right" and forbade further productions or publication of the script. Upon release of the film, however, he did authorize an illustrated paperback tie-in edition of the screenplay, published by Lancer Books. Justin Playfair (Scott) is a millionaire who retreats into fantasy after the death of his wife, imagining himself to be Sherlock Holmes, the legendary fictional detective. Complete with deerstalker hat, pipe and violin, he spends his days in a home-made criminal laboratory, constantly paranoid about plots hatched by his (Holmes's) arch-enemy, Professor Moriarty. When his brother (Lester Rawlins) places Justin under observation in a mental institution, and conspires with his former business associate to get power of attorney, Justin attracts the attention of Dr Mildred Watson (Woodward), a psychiatrist who becomes fascinated by his case.
