Now, let's move onto some concept art for the WORLD of Oz.
Right from the off, I needed to figure out a way to make the Emerald City as huge and impressive and GREEN as people want it to be, while maintaining the reveal in the books that the whole city is actually NOT green, but an illusion. In the books, everyone who enters the city is given green tinted glasses - but this element has almost never been adapted. Oddly in the broadway version of Wicked, the characters do wear the tinted specs during the Emerald City song, but they don't comment on it.
So while it is very obviously stealing the idea from Doctor Who a little bit, the idea of a glass dome protecting the truth to the outside world made sense. Here is the first concept are we commissioned from the talented Cécile Carre.
