I recommended it to the Amnesty International club on campus.
A Little bit about the event that was not in the film (I have done lots of searches on this event but have been limited by my English).
The teacher accepted the bribe that he refused in the movie. I can't blame him for it as he really was in bad straights in his home life.
The teachers went back to teaching at the school.
Kids from this case were in the movie as extras.
