Yep all of it ...

Emma Watson's wasn't a good enough singer to pull of Belle, but was a Big Name.
Will Smith isn't a good enough singer to pull off Genie.

Les Mis the movie had some big names who were just there for big names reason not for musical reasons.
Phantom of the Opera .... etc etc etc ...

Lots of cases of Hollywood getting the Big Name FACE rather than the Strong VOICE.

WORST was LaLaLand which was all about MUSIC and got a Pretty Face rather than a Strong Voice.
