Animation voiceover veterans of the era chimed in with narration or voices for other characters; for instance, the indefatigable Paul Frees does the narration on Phinkfinger, a funny spoof of 007-style spy movies. But most of the cartoons are wordless, which is one reason they remained popular internationally for so many years. The main reason is the slinky character of the Panther, a mischievous hipster who could be either the instrument of chaos or the victim, depending on the cartoon. The plots tend toward the cartoon verities: the necessity of catching a mouse or silencing an alarm clock, for instance. A documentary, Behind the Feline, gives a fine account of the history of the character; it is also bundled on a previous boxed set, The Pink Panther Film Collection. Useful new extras include a portrait of Friz Freleng by his daughters, an illuminating interview with animator-director Art Leonardi, and a delightful vignette with Leonardi instructing us on how to quickly draw the Pink Panther. The opening-title sequences from five Pink Panther movies are included. Throughout the cartoons and the extras, you will be reminded of one incalculable boost to the series: Henry Mancini's lithe, foxy theme music, which surely had much to do with the character's enduring fame. Mancini gets an onscreen shout-out in Pink, Plunk, Plink, in which the Panther tries to inject his theme into an orchestral performance of Beethoven's Fifth. --Robert Horton
