The Pink Panther is a series of comedy films featuring the bumbling French police detective Jacques Clouseau. The role was originated by, and is most closely associated with, Peter Sellers. Most of the films were directed and co-written by Blake Edwards, with notable theme music composed by Henry Mancini.Despite its use in the titles of most of the films of the series, "The Pink Panther" is not the Clouseau character, but a large and valuable fictitious diamond which is the "MacGuffin" of the first film in the series. It bears that name because the flaw at its center, when viewed closely, is said to resemble a leaping pink panther. The phrase reappears in the title of the fourth film, The Return of the Pink Panther, in which the theft of the diamond is again the center of the plot. The film marked the return of Sellers to the role after a gap of ten years. The phrase has been used for all the subsequent films in the series, even when the jewel does not figure into the plot (the diamond has only appeared in five of the ten films in the series).
