Milana Vayntrub has been cast as Squirrel Girl in the forthcoming Marvel series New Warriors, and people are freaking out (with mostly positive reactions). The show’s storyline will follow a group of six young adult superheroes, but the hype has been pretty much all about Squirrel Girl from the beginning, so this casting choice is big news.

New Warriors will premiere on Freeform sometime in 2018.
