I doubt the original Oz would even be an option. If for some reason it was, the reaction would be worse than both SOM and PP. There would be so much comparing to the performances everyone already knows and loves, too big of shoes to fill.
I believe this year marks the 40th anniversary of the original Broadway production of The Wiz. It would be great if they could bring together a couple cast members (from either Broadway or the film) to be a part of a broadcast if it happens. Stephanie Mills, Hinton Battle, Dee Dee Bridgewater, Andre De Shields, and Diana Ross and Phylicia Rashad are still around.
I am big. It’s the REVIVALS that got small.
