The Pink Panther derives its name from the eponymous pink diamond that has an enormous size and value. The diamond is called the "Pink Panther" 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 centre of the plot. The phrase was used for all the subsequent films in the series, even when the jewel did not figure in the plot. It ultimately appeared in six of the eleven films.
