Variety has reported that Warner Bros. finalized a deal with Japanese publisher Kodansha to produce a feature film based on Hajime Isayama’s Attack on Titan manga. Andy Muschietti is on board to direct.
David Heyman, Masi Oka, and Andy’s sister Barbara Muschietti are producing the film.
Deadline Hollywood reported in January 2017 that Warner Bros. was in negotiations to get the film rights (with Heyman on board to produce), but Kodansha claimed that the report was incorrect.
