Update From OSC
Orson Scott Card posted on his official forum, Hatrack, some details about the EG Movie:
1. We compress the action of the book to one year, and the youngest of the characters (Bean) is about nine or ten.
2. It's very hard to work with child actors, but it can be done, as witness the stellar performances of every child actor in Peter Pan and Neverland.
About Wolfgang Petersen:
Writers don't "pick" directors. The only power I had was to veto the ones who would have been horrible. Beyond that, we looked for directors who found the project interesting, who were on the short list of those capable of directing it AND of getting a studio to back the project with that director attached. What some folks don't seem to grasp is that the ONLY reason Warner Brothers picked up the Ender's Game movie project was that Wolfgang was attached. If Wolfgang were not the director, THERE WOULD BE NO PROJECT. We'd still be going begging to the studio doors. Wolfgang, not I, is driving the project. That's how Hollywood works, when it works at all.
... you want a director who can't bear a tough ending? A director who has no understanding of character? I'd rather NOT see Ender's Game be nothing but a special effect-driven extravaganza, thanks ...
