Friz Freleng and David DePatie began their new studio auspiciously with this film and its Oscar-winning predecessor, "The Pink Phink" (as well as the first live-action movie's opening which started it all--probably the single greatest thing Freleng ever directed).
I really wish Freleng hadn't tinkered with such a superb formula: in "Pink Pajamas," his flair for pantomime humor and comic timing is completely intact. Nearly everything happens spot on, in a thoroughly inevitable way. Writer John Dunn's gags are more than just serviceable.
But Freleng dinkered with the series's format for the rest of his directed filmography, even having the panther (heaven help us all) TALK, fer cryin' out loud! In a couple of years Freleng would hand over the directorial reins to long-time layout man and character designer, Hawley Pratt (really the TRUE creator of the Pink Panther). Pratt fortunately stuck to the pantomime formula and kept the series on an even keel with some very good cartoons.
I guess Freleng's main job at his own studio now was "minding the store".
