In a Furiosa screening, I was surprised at how big the reaction was to the Wicked trailer. It was almost the same level as DP. I'm sensing serious Barbie vibes here as a huge rush event.

Considering she is canonically green, and there were no green actors available to play the part, I'm sure they will be just fine with it.

I'm more surprised that they chose someone who looks middle aged like Erivo

Yeah Ariana at least (somewhat infamously) looks much younger than her age, but Erivo looks 40. It's a strange casting decision.
