!!Expect unmarked spoilers. Best if youread this page after you have seen the movie.
* As Professor Keating leaves his classroom for the last time after the school fires him for [[spoiler: Neil's suicide]], the remaining members of the Dead Poet's Society all stand on their desk, look at him, and say "Oh, Captain, my Captain!". There were members of the class who WEREN'T members of the Society, meaning that it wasn't JUST the DPS that took Keating's message to heart. Total [[SugarWiki/HeartwarmingMoments heartwarming]].
* Todd after learning of [[spoiler:Neil's death,]] walking in the snow, looking around and commenting on the beauty of it... before ''practically vomiting with grief'' and then charging away across the field ''screaming'' Neil's name.
* Keating when he sits at the desk that had been Neil's and flips through the book that he himself used as a member of the Dead Poets Society before breaking down and weeping.
* Neil's sadness when his father tells him "I don't care if the world ends tomorrow night, you are through with that play!" Topped only by his [[spoiler: suicide]]. While his father is clearly having an ItsAllAboutMe moment, his mother looks genuinely distraught.
* If you look really closely at Neil's father after the play, when he's berating Neil about wanting to be an actor and asks him why he wants to do it, he looks more frustrated than angry as if he really wants to know why. Which makes his reaction to Neil's [[spoiler: suicide]] that more heart-wrenching, because you wonder if he wanted to fix his relationship with his son and now he's lost his chance.
* Neil's father turning up at the opening night for the play, waiting until it is done, then taking him back to their house without a word of congratulation. The others try to tell him that his son has done well, but Keating tells them dejectedly "don't make it worse than it already is". He obviously agrees with them, but is GenreSavvy enough to know it's too late.
* A very subtle one occurs after [[spoiler:Neil's death]]. At his [[spoiler:memorial service at the school]], the dead poets are seen in a line, singing wistfully. All except Charlie, who stares forward, angry and unmoving and silent.
