Director Andy Muschietti has found his follow-up to the It franchise.


The filmmaker is developing an adaptation of the popular manga series Attack on Titan for Warner Bros.


Hajime Isayama created the manga, which debuted in 2009 and takes place in a world that has been overrun by Titans — giant, mindless human-eating creatures. Humanity is forced to live in cities built behind giant walls that keep the Titans at bay. Attack on Titan at times can be quite gruesome and deals with themes such as militarization, the horrors of war and abuse of power. It has been adapted into an anime series that launched in 2013 as well as into a two-part, live-action film in 2015.


The new feature version comes from Harry Potter producer David Heyman, who is producing along with Masi Oka and Barbara Muschietti. No screenwriters are attached.


Andy Muschietti, who rose to prominence with the 2013 horror film Mama, broke out in a big way with last year's It, which earned more than $700 million globally and boasts the top opening for an R-rated horror movie of all time. He is currently working on It: Chapter Two, which Warners is set to open Sept. 6, 2019, and stars James McAvoy, Bill Hader, Jessica Chastain and Bill Skarsgard as Pennywise.
