Debuting in 2009, "Attack on Titan" is a post-apocalyptic fantasy set in a world where remorseless, flesh-eating giants have all but wiped out humanity, whose remnants are forced to live within a country surrounded by three enormous walls. The story initially centers on Eren Yeager, his adopted sister Mikasa Ackerman and their childhood friend Armin Alert, who join the military to fight the Titans after their hometown is attacked and Eren's mother eaten.

A Japanese live-action adaptation, spanning two films, is set to premiere this summer. The first season of the blockbuster anime series has also been adapted for theatrical release, with the first 13 episodes combined and abridged as "Attack on Titan: The Crimson Bow and Arrow," debuting last fall; the second part, "Wings of Freedom," will arrive in June.
