With just under three months to go before Ender's Game hits theaters, Summit Entertainment has debuted the final trailer for this sci-fi adaptation, following the trailer preview that debuted yesterday. The story, based on Orson Scott Card's seminal novel, is set in a future where aliens known as the Formics have decimated the planet, leading to the formation of the International Fleet and the Battle School, where the best and brightest young soldiers train to be the future leaders of the fleet and bring down this alien scourge for good. Asa Butterfield stars as Ender Wiggin, who may be the next great fleet leader, with Harrison Ford and Ben Kingsley starring as Colonel Hyrum Graff and Fleet Commander Mazer Rackham. Take a look at the latest footage from director Gavin Hood's adaptation, in theaters November 1.

In the near future, a hostile alien race called the Formics have attacked Earth. If not for the legendary heroics of International Fleet Commander Mazer Rackham, all would have been lost. In preparation for the next attack, the highly esteemed Colonel Hyrum Graff and the International Military are training only the best young minds to find the future Mazer. Ender Wiggin, a shy but strategically brilliant boy, is recruited to join the elite. Arriving at Battle School, Ender quickly and easily masters increasingly difficult challenges and simulations, distinguishing himself and winning respect amongst his peers. Ender is soon ordained by 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 his fellow soldiers into an epic battle that will determine the future of Earth and save the human race.
