American audiences who may not be up on their manga game probably don't realize the excitement building for a live-action Attack on Titan film. The project has been in the works for four years and seen a couple of directors come and go, but with Shinji Higuchi (The Floating Castle,which you should definitely check out) at the helm and collaborating with series creator Hajime Isiyama, Attack on Titan is not only a reality but the first teaser has hit.
Attack on Titan takes place in a world that has humanity living in cities surrounded by massive walls to defend against the invading Titans, gigantic creatures that kill people for mysterious reasons. The attacks have decimated the human population, but a resistance is formed to fight back and reclaim the world.
Isiyama has been working with Higuchi to create new creatures and characters, so there will be something fresh for fans of the manga. It's set to be released on August 1st, but this is only the first film in what is expected to be a two-part epic with the second film released a month later.
