The movie, which is set for release in 2013, is based on Orson Scott Card's 1985 science-fiction novel about a war between aliens and humankind that is set in the future.
Ford will play Colonel Hyrum Graff, the head of the Battle School that Ender attends. Hugo star Asa Butterfield will play "Ender" Wiggin, who is called upon by Col. Graff to save humankind from an alien invasion. Breslin's role in the sci-fi film has yet to be confirmed but she will most likely play Valentine, Ender's older sister.
The film will be directed by Gavin Hood, who directed X-Men Origins: Wolverine. Summit Entertainment is planning to release the film on March 15, 2013.
