Set in the near future after a hostile alien race has attacked Earth, Ender's Game follows the recruitment and rigorous training of one Ender Wiggan, a shy-but-strategically brilliant boy who is put through the paces at Battle School in outer space. Can he rise through the ranks and demonstrate a fierce ability to out-think those who are more physically imposing while maintaining his emotional state of mind? Based on the bestseller by Orson Scott Card and directed by Gavin Hood, Ender's Game also co-stars Hailee Steinfeld, Ben Kingsley, Viola Davis and Abigail Breslin.
