Box Office Bomb: The film was budgeted at $110 million not counting publicity, and it only made back $112 million worldwide. This is partially due to the tight competition it faced from Thor: The Dark World. The backlash the film received from the LGBT community due to Card's less-than-favorable views on homosexuality and gay marriage did not help Lionsgate one bit.
Development Hell: The film was mired there for decades. Unusually, Card was partially involved in keeping it there, as he preferred having no film than having one with a poor script and a bad child actor in the main role.
Card: My favorite thing about the end of 2013: I will never again have to answer questions about when the Ender's Game movie will come out.
Enforced Method Acting: The film was shot in sequence with Ford keeping his distance from Butterfield and the other kids at first so that their being in awe of The Harrison Ford (as well as their physical growth) would work for rather than against the story.
Executive Meddling: Ender's Shadow was originally titled "Urchin". That title was re-included as that of the first chapter.
An accidental example: Card intended for only Speaker For the Dead and Ender's Game to be written. His agent accidentally pitched them as "the Ender trilogy", and Card decided to use the opening to write Xenocide.
Inspiration For The Work: Orson Scott Card got the idea for Ender's Game as a kid, when he tried to theorize what the military of the future would use to train soldiers in space, thus imagining the Battle Room. That manifested into the original short story, but the full novel didn't emerge until he was trying to decide who would be the protagonist of Speaker for the Dead, when his wife suggested it could be Ender.
Playing with Character Type: Harrison Ford is known for playing heroic characters, among them Han Solo, a Jerk with a Heart of Gold that was likable. Ford's portrayal of Graff is just the opposite - a cold, calculating figure that isn't concerned for the safety of his cadets so much as he's concerned with overwhelming an alien race.
Stillborn Franchise: Plans were made for a sequel, but instead of being the start of a new film franchise, the film adaptation could end up serving as a prime example of why creators of potential franchises should watch their mouths in the future.
