The movie is being developed and produced by Erik Feig under his Picturestart studios launched in 2019 in collaboration with Scholastic publishing. Feig is the former president of Lion's Gate and Summit Pictures, famous for that mid-2010s run of successful YA adaptations and star-creating vehicles like Twilight, Hunger Games, and Divergent.
Scholastic is also developing a series of graphic novel adaptations of the series, the first of which will be released October 6th, and a Retro Box Tin of the first six books in the series some time in the fall.
I am going to be excited about this before I inevitably collapse into dread once they start announcing directors and releasing promotional shots!!!!
