A very funny comedy which marked the directorial debut of Gene Wilder, who also wrote the screenplay. The plot has Sherlock involved in a very important case. So that he can solve it without criminal interference, he uses his younger brother Sigerson (Wilder) as a decoy. Sigerson believes his brother needs help with the case, and sets out to solve it. Madeline is his romantic lead, the mysterious Jenny Hill. Also featured are fellow Mel Brooks favorites Marty Feldman and Dom DeLuise. Madeline has some terrific singing scenes, and some genuinely hilarious moments with Wilder. Classic.
