1. Max Charles (Kion), Maia Mitchell (Jasiri), and Christian Slater (Ushari) share the same birthday: August 18th. Charles had been born on Mitchell's tenth birthday, and Slater's... 34th?
2. Similarly, Eden Riegel (Kiara) and Diamond White (Fuli) share another: January 1st. All of White's life, Riegel was always at least legally a woman, seeing as she had turned 18 on the day White was born.
3. Sarah Hyland (the initial voice of Tiifu) and Ernie Sabella (Pumbaa, as usual) had both appeared in Disney's 1999 TV film adaptation of Annie, as Molly and Mr. Bundles, respectively.
Any other connections to point out?
