This movie, The Pink Panther Strikes Again (1976) is a family favorite! While the film itself is live action, I’ve always been a fan of the into and outro animations. The pacing is really well done, and I think the animations themselves are very clever. Many of the Pink Panther films have these animations as intros.
Here’s another, from Revenge of the Pink Panther (1978). I think this one is a bit more interesting when it comes to the animation, particularly the flashlight and incorporation of the credits text into the scenes.
