re: Ender's game movie finally a reality.

I think the only scene that is unfilmable is the shower scene. It's crucial to the plot and unless you are marketing the film to Jerry Sandusky, you have to change some important details.

I've heard the plan is to change Ender to about 10 in the beginning, which is doable without rendering the story invalid. You're still stealing a child away from his parents before the age of consent and before he really understands what is going on (not a spoiler, this happens in the first 10 pages).
