Don't get your hopes up to high. Ender's Game is probably my favorite Sci-fi novel as well, and though they did an admirable job with the movie, it's far too rushed. I desperately wish they would have taken a cue from Peter Jackson and broken it into two movies. Part One could have taken us through Launch School and climaxed with the fight with Bonzo, then Part Two could start with the transfer to Command School. Would have worked so much better.
