Sherlock Holmes (a.k.a. Conan Doyle's Master Detective Sherlock Holmes) is a 1932 American pre-Code film starring Clive Brook as the eponymous London detective. The movie is based on the successful stage play Sherlock Holmes by William Gillette, in turn based on the stories by Arthur Conan Doyle, and is directed by William K. Howard for the Fox Film Corporation. Brook had played Holmes previously in The Return of Sherlock Holmes and the "Murder Will Out" segment of Paramount on Parade.Reginald Owen plays Dr. Watson, and Ernest Torrence is Holmes's arch-rival, Professor Moriarty. Reginald Owen played Sherlock Holmes the following year in A Study in Scarlet. Owen is one of a small number of actors to play both Holmes and Watson. Examples of other such actors include Jeremy Brett, who played Watson on stage in the United States and, most famously, Holmes on British television, Carleton Hobbs, who played both roles in British radio adaptations, and Patrick Macnee, who played both roles in US television movies.
