Honestly, I'm kinda concerned about them getting JEJ back as Mufasa. I get why they did it, obviously, but his voice was clearly showing its age in what few lines Vader had in Rogue One. Mufasa is going to have a considerably larger number of lines than that, even with his early death in the film. There were absolutely other actors they could've gotten to replace him as Mufasa, just like with Scar and Zazu.
That said, I'm fond of this cast overall. Beyonce is sort of a reverse situation to what I had with Emma Watson being cast as Belle in the B&TB remake; there I figured Watson would be able to act as Belle but would struggle with the singing (and I ended up feeling a bit let down on her acting performance too tbh), whereas here I
know Beyonce is going to rock the hell out of any and all songs that Nala sings in the film. If Favreau is smart, he brings over Shadowland over from the Broadway version so that Beyonce can have that solo moment. But like everyone else, I am a bit concerned about her acting.
Donald Glover though is a straight up improvement in every regard for Simba. He's going to
own The Lion King.
His singing is....decent at best.
Lies and slander, yado!!! D:
