I've never read the book, but it's worth reminding everyone again that this movie likely isn't going to follow it super close...
I'm sure it will be a lot like the Ender's Game movie. They will get most of the main stuff and characters in there, but they will have to rush or simply skip so many details that it will feel very shallow for those that read the book.
Much like Enders Game, so much of the story revolves around the journey/growth the protagonist takes over a period of time (as opposed to a more confined and short time frame). And more importantly, the protagonist interacts with several characters along the way and they are all key. That's hard to do for a movie. I know for Enders Game it felt like they simply went from one plot line to the next (checking boxes) until they got to the climax and then roll credits.
I'm still excited for it though!
