Marvel's Moon Girl and Devil Dinosaur Started Out as a Different Disney Spinoff

Marvel's Moon Girl and Devil Dinosaur will drop its second episode today, but it was almost an entirely different show. Not in terms of stylistic choices or casting, but a literal different show, based on an entirely different property. And it's kind of hard to believe where it started: the world of Cars. Yes, that's right: according to executive producer Steve Loter, the designs that became Moon Girl and Devil Dinosaur's highly-stylized version of New York City originally started on Metro, a movie set in the same world as Disney and Pixar's Cars and its spinoff Planes.

Loter, who says he still hopes to finish the movie someday, shared a couple of pieces of concept art that would have been used to make Metro. It was also far enough along that he knew who was supposed to star.

"Moon Girl and Devil Dinosaur started with my unfinished Cars World film, Metro," said Loter on social media. "We developed a graphic dynamic representation of New York that has had elements carry over to MG. Jermaine Fowler would have been the lead character and Raphael Saadiq would have done the songs and score."
