"Welcome to Battle School, a great responsibility rests upon each of you. When the enemy first invaded, we were not ready. Millions of innocent lives were lost. That must never be allowed to happen again!" Harrison Ford's Colonel Graff tells his young cadets as they prepare for battle training in the first clip from Ender's Game. Gavin Hood directs this adaptation of the young adult sci-fi novel, which makes its Comic-Con 2013 presence known with a panel on Thursday at 3:50 in Hall H.

After an alien race called the Formics attacks Earth, the International Fleet prepare for the next invasion by training the best young children to find the future leader to lead the International Military. Ender Wiggin, a shy but strategically brilliant boy, is pulled out of his school to join International Fleet and attend the legendary Battle School. After easily mastering the increasingly difficult war games, distinguishing himself and winning respect among his peers, Ender is soon ordained by Colonel Graff as the military's next great hope, resulting in his promotion to Command School. Once there, he's trained by Mazer Rackham himself to lead the military into a war that will determine the future of Earth and the human race.
