I'm not sure about this as a film, not just by the likes of Disney.
I know the screenplay has been written by Card himself, it's just that like Discworld there is a lot going on in the background and sooooo much of the story involves the violence and the way Ender is treated and of course Bean's back story as well.
I think this will be too toned down so it can get a 12 rating it won't even be worth buying, let alone wasting time in the cimena. Also no official trailer, the film must be pants then... Disney should have the marketing machine going full blast by now, cheap Chinese made toys in the Maccy D kids meals, play the Ender board game, beat your way to the top. Bet the aliens won't get called Buggers at any time during the film.
Loved the books, think not for the film.
