Attack On Titan is the closing night film at the Fantasia Festival...which means we're about to hear many more things about this movie.
Here is the movies plot in case you haven't seen the Anime series :
“for one hundred years, humanity—or what remains of it—has existed within the protective confines of the three great walls. The towering structures were built to resist the hordes of Titans, horrific humanoid giants that arrived inexplicably and seemed to have no other purpose than to savagely devour men, women, and children. A century of security and peace is shattered when a particularly large and grotesque Titan breaches a section of the outer wall.”
