The latest Ender's Game trailer debuts tomorrow, but before that arrives online, we have a trailer preview featuring the latest footage from director Gavin Hood's adaptation of Orson Scott Card's sci-fi novel. Harrison Ford and Ben Kingsley star as Colonel Hyrum Graff and Mazer Rackham, who train the best and brightest young men and women at the Battle School to find the International Fleet's future leaders in their war against a deadly race of aliens known as Formics. Take a look at the latest footage, also featuring Asa Butterfield as Ender Wiggin, then check back tomorrow for the full trailer.

In the near future, a hostile alien race 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 Graff and the International Military are training only the best young children to find the future Mazer. Ender Wiggin, a shy, but strategically brilliant boy is pulled out of his school to join the elite.

Arriving at Battle School, Ender quickly and easily masters increasingly difficult war games, distiguising 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.
