The Adventure of Sherlock Holmes' Smarter Brother (1975)

Gene Wilder directed and starred for the first time. Describe the foolish brother of Sherlock Holmes, who was lucky enough to deal with a disguised opera actress and a ubiquitous professor, thus solving a mysterious international espionage case. Following the style of his master, Mel Brooke, the director joked about Sherlock Holmes movies, but most of the scenes were aimless, and only a few scenes showed comedy brilliance.
