Ford will play Colonel Hyram Graff, who's in charge of training the young male recruits at an elite military academy. Breslin will play Valentine Wiggin, Ender's older sister, while Steinfeld will play Petra Arkanian, Ender's ally and trusted right hand.
Knight, who previously appeared in Hood's "Rendition," will play Bean, the smallest new recruit; Arias ("Hannah Montana") will play Bonzo, the commander of Salamander Army; Pinchak ("Let Me In") will play Peter Wiggin, Ender's brilliant but tortured older brother; and Parthasarathy will play Alai, the first recruit to befriend Ender.
Carroll ("Away We Go") will play Bernard, the leader of the new recruits who bullies Ender at first; and Rhambo will play Dink, a brainy member of Rat Army.
Well, that's some gang of new cast members. If you haven't read the novel it involves the recruiting of extremely gifted children (the most gifted of which is the title character Ender Wiggin) by the government to help destroy an insect-like alien race. I was not very impressed by Ford's last outing taking on aliens so hopefully this will be a return to form for a man who has played some of the most iconic characters in movie history.
