MAJOR SPOILER IF YOU PLAN ON WATCHING THIS MOVIE SOON!
Absolutely amazing acting. Pacino does another fine job in this movie, but this ending scene is where he really delivers his best. Basically, he's being asked to defend a high profile judge who has been asked of sexually assaulting a woman. All the time he believed his client was innocent. It's only before the trial that he finds out he is in fact guilt. So, what does he do?
