Its a really nice indepth story of how the movie came to pass involving alot of research and plot changes and such like. And honestly having seen it im glad the film turned out the way it did. I think the collar deal was an unecessary evil. As someone who has seen the school teachr documentary himself, i have seen the effects of labeling certain people as inferior even if the label is meant to be for their own good or whatever. Heck i myself have delt with being labeled and lumped into a specific group. I honestly believe i would not have enjoyed the movie as much as i did and think the way they went with it in the end was better.
