most emotionally devasting moment in film

[Michaelson]

Pretty much everything in this thread will be a spoiler, so it's probably best to name the movie first then discuss the scene. If I were in Seabeast's shoes I would be twice as pissed.

The Thin Red Line: there is a scene when one of the privates, who has been using the memories of his wife back home as motivation to get through his tour, receives a dear john letter... it sends a chill down my spine every time I see it, even though I expect it now. Absolutely gutting.
