Inspector Clouseau of the character. The film also introduces two of the series regular characters: his superior, Commissioner Dreyfus (Herbert Lom), who is driven mad by Clouseau's blundering of the investigation; and his long-suffering Chinese man servant, Cato (Burt Kwouk), who is expected to improve Clouseau's martial arts skills by attacking him at random. Sellers stepped away from playing the character following this movie, but returned in "The Return of the Pink Panther" (1975) and its sequels. When the character returned for the film "Inspector Clouseau" (1968), he was portrayed by American actor Alan Arkin; Edwards was not involved in this production.
A Shot in the Dark (1964 film) as Burt Kwouk as his stalwart man servant Cato and André Maranne as François, all of whom would become series regulars. Elke Sommer portrays the murder suspect, Maria Gambrelli. The character of Gambrelli would return in "Son of the Pink Panther" (1993), this time played by Claudia Cardinale, who appeared as Princess Dala in "The Pink Panther" (1963). Graham Stark, who portrays police officer Hercule Lajoy, would reprise this role eighteen years later, in "Trail of the Pink Panther" (1982). The film was not originally written to include Clouseau, but was an adaptation of a stage play by Harry Kurnitz
