The second time a bomb goes off in Breakfast On Pluto, the dancing scene, cuts me up.
The ending of The Butcher Boy.
The overpass scene in American Splendor.
The ending of Fearless by Peter Weir, starring Jeff Bridges.
From imdb :
After a terrible air disaster, survivor Max Klein emerges a changed person. Unable to connect to his former life or to wife Laura, he feels godlike and invulnerable. When psychologist Bill Perlman is unable to help Max, he has Max meet another survivor, Carla Rodrigo, who is racked with grief and guilt since her baby died in the crash which she and Max survived.
The ending of that movie just kills me :
Max has been allergic to strawberries all his life but now thinks it can’t kill him, or maybe he just doesn’t care anymore.
The way he lies on the floor and just starts sobbing uncontrollably for the first time in the movie : “Help me”.
I get teared up just writing about it.
Brian’s Song
THe scene in Crusoe where his dog dies.
The end of Castaway when he comes back to Kelly, only to find that she’s moved on. The scene where they hug in the rain makes me cry every time.
The Plague Dogs. Holy crap. If that movie doesn’t make you bawl, then you’re not human. “Look, Snitter. It’s. . . our. . . island. . .” 
Highlander - The ‘montage’ scene where his wife eventually gets old and dies yet he doesn’t age (to the tune of Queen’s ‘Who Wants To Live Forever’ playing).
The scene in My Girl after Culkin’s character dies and the main girl throws herself on his coffin at the funeral begging him to wake up.
The whole ending of “Big Fish”.
The final scene of Dancer In The Dark left me literally bawling uncontrollably for about a half hour. I’m haunted still by it.
My son, a Bjork fan, somehow convinced me, (NOT a Bjork fan) to watch this movie. It’s a musical of sorts, which we are neither fans of. But for this movie, with this character, it works. Once I got accustomed to the Bjorkiness, it turned out to be the saddest movie ever. This one’s guaranteed to turn the toughest tough guy into a weeping puddle of goo.
sad?
I came in here to post this. The scene where Celie and Nettie are separated makes me cry. The ending when they reunite and Celie sees her long lost children is a half box of tissues cry.
Haven’t any of you people seen Old Yeller?
An oldie but goodie - I’m 45 and have seen Bambi more times than I can count, but Bambi wandering in the woods in the snow calling for his mother has me bawling every single time.
The last time there was a thread like this, I mentioned Akira Kurosawa’s Ikiru. There’s just something about his cinematic technique that pulled on my cynical little heartstrings.
Well, it made me cry. I did see it not too long after my father died. My girlfriend at the time said she knew that I was going to end up sobbing as we watched it, considering I had recently lost a father who I never really connected with or knew well.
Withnail reciting Hamlet’s speech to Rosencrantz and Guildenstern at the end of Withnail & I. Poor fucking bastard.
The scene where the band plays outside the bandleader’s window in “Brassed Off”. Came out of nowhere.
A recent one for me was Wall-E
The part where you think he’s “dead” and Eve’s reaction to that was sad, but not enough to make me tear up. The part that got me was when she fixed him, but he wasn’t him anymore. He didn’t know who she was, and he didn’t have his quirky personality anymore. He was just a robot. That tore me right up.
Well I am one of the few who think A.I. is a brilliant movie and one reason is because how it plays with your emotions.
When the mother leaves the robot boy in the woods it is extremely sad…yet, it isn’t, because after all he is a machine. And the emotions the mother is going through are also confusing, you are sad for her, yet you also want to say…stop it, it’s NOT A BOY!
I will second the ending scene of Dancer in the Dark. I think it scarred me for life.
For second place, though, I’d like to nominate the scene in The Piano where:
Sam Neill cuts off Holly Hunter’s fingers. Pure evil.
The ending of Watership Down.
