SDCC gave us our first clip from Ender's Game, featuring Harrison Ford as Colonel Graff, welcoming the new round of cadets to Battle School.
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 (Asa Butterfield), 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 (Harrison Ford) as the military's next great hope, resulting in his promotion to Command School. Once there, he's trained by Mazer Rackham (Ben Kingsley) himself to lead the military into a war that will determine the future of Earth and the human race.
Starring Asa Butterfield as Ender Wiggin, Harrison Ford as Colonel Graff, Ben Kingsley as Mazer Rackham, Abigail Breslin as Valentine Wiggin, and Hailee Steinfeld as Petra Arkanian. In theaters November 1st, 2013.
