idk if anyone else will like this but, I think this would be really cool. Ok, so at the end of part 2 during the credit sequences we need to see photos and video footage of Michael Jackson performing on stage and behind the scenes of his music videos. This is typical for biopics musical and non musical alike. Most biopic films include photos and video footage of the actual individuals depicted in the film as a way to pay homage and show respect to the individuals legacy. Have the credits roll with this imagery spliced in as a way to still keep audience members engaged as the film has come to a close.
Then boom post credit scene:
We see Jafar dressed as Michael in his thriller aesthetic with Asia Fuqua who is still dressed as Ola Ray and they reenact the ending scene from the Thriller music video.
Jafar as Michael: It's only a movie, I'll take you home.
Jafar then looks back at the camera and we hear the evil thriller laugh track.
I might be the only one that sees this vision but, to me that moment is just too perfect to not recreate. It's a special 4th wall break kinda thing. It's a nod to say even from the grave Michael is still entertaining us all these years later.
