After several years of speculation on the possibility, Summit Entertainment financed and coordinated the development of a film in 2011, serving as its distributor. Gavin Hood directed the film, which lasts 1 hour and 54 minutes. Filming began in New Orleans, Louisiana, on February 27, 2012, and was released on November 1, 2013 (USA). A movie preview trailer was released in May 2013 and a second trailer was released later that year.
Card has called Ender's Game "unfilmable", "because everything takes place in Ender's head", and refused to sign a film deal unless he could ensure that the film was "true to the story". Of the film that he eventually agreed to, Card said it was "the best that good people could do with a story they really cared about and believed in", and while warning fans not to expect a completely faithful adaptation, called the film "damn good".
The movie starred Asa Butterfield as Ender Wiggin and Harrison Ford as Colonel Hyrum Graff. It grossed $125 million worldwide, and received mixed reviews from critics.
In 2008 it was announced an Ender's Game video game was in the works. It was to be known as Ender's Game: Battle Room and was a planned digitally distributed video game for all viable downloadable platforms. It was under development by Chair Entertainment, which also developed the Xbox Live Arcade games Undertow and Shadow Complex. Chair had sold the licensing of Empire to Card, which became a best-selling novel. Little was revealed about the game, save its setting in the Ender universe and that it would have focused on the Battle Room.
In December, 2010, it was announced that the video game development had stopped and the project put on indefinite hold.
Orson Scott Card and Amaze Entertainment also came to an agreement regarding a video game adaption of the novel but nothing ever materialised.
Marvel Comics and Orson Scott Card announced on April 19, 2008, that they would be publishing a limited series adaptation of Ender's Game as the first in a comic series that would adapt all of Card's Ender's Game novels. Card was quoted as saying that it is the first step in moving the story to a visual medium. The first five-issue series, titled Ender's Game: Battle School, was written by Christopher Yost, while the second five-issue series, Ender's Shadow: Battle School, was written by Mike Carey.
