Why waste a good thing?
Disney doesn’t only recycle stories from other sources, but also recycles from their own films! In The Lion King, for instance, some of Mufasa’s vocalizations were taken from The Beauty and the
Beast (the voice of the beast, obviously).
Even more impressive, they recycle specific shots from different movies. In a countless number of films, you can identify identical gestures performed by different characters. Next time you watch a Disney film, try to notice this.
