Kill Bill: Spoiler: When The Bride enters Bill's condo, walks through with a gun, and walks outside. Her daughter and Bill are outside pointing the toy guns at her, saying "BAM!". Bill falls to the floor, playing dead, so does B.B. The Bride has tears rolling down her face. She realizes that B.B. is her daughter. That whole sequence, even the "Shogun Assassin" sequence was absolutely touching.

In "The Hours"...the scene on the platform at the train station between Virginia and her husband...and also the last scene between Clarissa and Richard.

No!!! I looked at the spoiler because it was labeled "Kill Bill" (which I've seen) instead of "Kill Bill 2," which I haven't seen! Beware!

In the never ending story when atreyu is leading artex through the swamps of sadness and he starts to sink. Jesus is that sad, but the most moving moment ever captured on film is the israeli army killing a palestinian man and his son who are hiding behind a piece of concrete. That clip would drive me to kill the people doing it.

I saw that one, that was really sad. I can relate, that guy reminded me a lot of my dad. He's big on animals, loves them to death.

After seeing that movie many, many times, I'm still moved by the former cowboy asking Doc why he's involved and sticking by Wyatt Earp's side.
"Wyatt Earp is my friend."
"Well hell, I got lots of friends."
"I don't."

And that always sets me up to bawl hard at the end when Wyatt Earp says "Thanks for always being there, Doc."

Also, La Vita Bella, when Joshua finds his mother at the end. The kind of joy that makes you cry, you know.

God i feel like such a nerd for getting incredibly emotional during the whole Empire Strikes Back carbon freezing of Han Solo... the entire thing just gives me goosebumps.

Requiem for a Dream really destroyed my world for about two days, I couldn't sleep, didnt really eat... the entire movie was so powerful it killed me.

Old Boy, at the end when he opens the purple package and discovers the truth... great acting!

Two Towers, when Gandalf charges down the hill and the music is playing, and the sun beams over the hill, god i've got insane goosebumps just thinking about it... most powerful scene in the entire trilogy

Second to this would have to be Boromir's death, wow... Sean Bean has got to be one of my favorite actors all time.

Oh Platoon! Elias' death is haunting... just chills the bones, I am going to watch this movie tomorrow now just to experience it again.

Godfather, when Michael's wife (her name slipps my mind sadly) is outside his study, as the two goons pay their respects, and the doors close... wow, that's powerful!

For Love of the Game
(I am not an emotional person, but basically the whole end of the movie, no matter how many times I've seen it, has me bawling practically.

Casablanca
so many scenes, but my favorite one is where Rick and Victor are in Rick's office, and Victor is trying to get the exit visas. When into the bar come a bunch of Germans singing German songs about the piano. Victor heads down the stairs and has the band play Les Marseilles, and the entire bar basically out sings the Germans.... (OK, and get sthe bar shut down too)
Awesome movie if you haven't seen it.

The Shawshank, Private Ryan and Band of Brothers parts that have already been mentioned.

In "Full Metal Jacket" - the whole first scene when R. Lee Ermey starts yelling at the privates.

The Pianist - When Szpilman is asked to play the piano for the Nazi officer.

Blackhawk Down - At the end when they are cleaning up and eating one of the guys says "And someone is going to ask me why I went back in.... I'm not going to say anything, cause they just won't understand."

Schindler's List:
The very end of the movie, we're looking at his grave marker and the survivors are placing a single stone on top of his marker. The stones add up and the camera pulls back to show the line of people snaking off into the distance...

The full weight of what one person was able to accomplish is haunting.

"Stop...stop...will you? Stop, Dave...will you stop, Dave? Stop Dave...I'm afraid...I'm afraid...I'm afraid, Dave...Dave, my mind is going...I can feel it...I can feel it, my mind is going...there is no question about it...I can feel it...
"Good afternoon...gentlemen. I am a HAL9000 computer. I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January, 1992. My instructor was Mr. Langley and he taught me to sing a song. If you'd like to hear it I can sing it for you."
"Yes, I'd like to hear it HAL. Sing it for me."
"It's called 'Daisy':
Daisy, Daisy, give me your answer do
I'm half crazy all for the love of you
It won't be stylish marriage
I can't afford a carriage
But you'll look sweet upon the seat
Of a bicycle built for two..."

This scene hit me quite hard in a indirect manner. I was watching the movie together with my 4 year old daughter and towards the end, where the movies gets quite sad, i looked at her, and she had big tears rolling down her cheeks. She was quietly crying for the Giant... THAT choked me up :)

Lots of good ones have been posted... Don't know if someone mentioned it, but at the end of Apollo 13 when they were returning through the atmosphere, and 4 minutes had passed and everyone wondered whether or not they made it... Then the cameras picked up the return module parachuting down and Tom Hanks comes through on the radio, and everyone in the NASA control station jumps up and starts cheering. That makes me cry every time.

*Requiem For A Dream - it's hard to pick only one moment out of this movie, so i'll just name three :D. The entire end sequence, the first scene (where Harry and Tyrone take the tv from Harry's mother), and this following bit of dialogue -

Sara Goldfarb: I'm somebody now, Harry. Everybody likes me. Soon, millions of people will see me and they'll all like me. I'll tell them about you, and your father, how good he was to us. Remember? It's a reason to get up in the morning. It's a reason to lose weight, to fit in the red dress. It's a reason to smile. It makes tomorrow all right. What have I got Harry, hm? Why should I even make the bed, or wash the dishes? I do them, but why should I? I'm alone. Your father's gone, you're gone. I got no one to care for. What have I got, Harry? I'm lonely. I'm old.
Harry Goldfarb: You got friends, Ma.
Sara Goldfarb: Ah, it's not the same. They don't need me. I like the way I feel. I like thinking about the red dress and the television and you and your father. Now when I get the sun, I smile.

*Also, Amores Perros - the part where the "homeless" man comes back to his shed to find that the dog he saved had slaughtered the other dogs. It's crushing enough taken at face value, but when looking at it as a metaphor for humanity...

*Se7en - Mills' moment of realisation at the climax, the scene where Mills, Somerset and his wife are having dinner (these two being interrelated as one intensifies the impact of the other)

*Blade Runner - scenes already mentioned

*Donnie Darko - final scene where Gary Jules' cover of mad World starts playing...plenty of other great moments in the film but this is the best

There are many more from other movies I like but these are the ones I could think of off the top of my head.

The end of Ruy when he's carried off the field. Not a dry eye in the joint!

I love the part in ROTK where Sam carries Frodo up Mt. Doom. "I can't carry the ring, but I can carry you!"

I also love that part when they are lying on the rock with the lava coming down and they are discussing who they would marry.

I have to say the two scenes from animated movies that have been mentioned, The Iron Giant and Transformers, both get to me everytime.

I am also always moved by The Color Purple where Ceily and her children are reunited. I hold it together pretty well until the son says "Mama" in that odd African accent.

CHARIOTS OF FIRE
The moments when Eric Liddel is running and transforms into Spiritual Racer. He throws his head back, closes his eyes, and Vangelis' music changes gears along with him. When he makes this change, no mortal can outrun the guy, period.

Lately I have been thinking about a scene from Boogie Nights. It is not particularly moving, I just feel that it is extremely well done. The scene I am talking about is when the main character and his 2 junkie friends go to the drug dealer's house intending to rob him. They take a bag of fake cocaine to sell the guy in order to get inside. All three of them are strung out and the suspense in the room is almost overwhelming. The combination of the visual atmosphere, the nervous tics and twitches of the 3 junkies, and the crazy chinese kid randomly blowing up firecrackers was making me nervous. Everyone in the room knows what is coming except the drug dealer and the junkies are freaking out about the possibility of being found out about the fake drugs and nervous about the robbery. The drug dealer is high and very animated, making every one even more nervous. I think at one point he starts to wave his new gun around. The entire time his armed bodyguard is standing silently in the background. But I think the key aspect of the scene is the music. The drug dealer is blasting music out of his stereo. He keeps going on about his own personal mix tapes that are all these pounding 80's songs. At one point, the tape suddenly cracks to a stop, resulting in complete silence while it changes sides. Eventually "Sister Christian" comes on and the building crescendo before the "motorin' " part just takes the suspense thru the ceiling until the whole scene explodes.

I am the easiest guy on earth to get to cry...

The one that gets me more than any other, though, is in 'To Kill A Mockingbird' when all the black spectators in court stand up for Atticus Finch. Wow. Nowadays I start crying about 5 minutes early just anticipating it.

I'll second that. I used to cry as a kid when I'd watch that part.

The Day After Tomorrow
The last picture of the movie - the planet with the whole Northern Hemisphere covered in ice

In remember the titans when they win and when Julius goes to visit Gary and he says "Isn't it obvious, we are brothers"

All mentioned so far. The entire movie "What Dreams May Come True" hit me hard for some reason.

The final speech in Scent of a Woman is one of my favorite movie moments:

Trask: Mr. Sims, I will give you one final opportunity to speak up.

Slade: Mr. Sims doesn't want it. He doesn't need to labeled: "Still worthy of being a 'Baird Man.'" What the hell is that? What is your motto here? "Boys, inform on your classmates, save your hide" -- anything short of that we're gonna burn you at the stake? Well, gentlemen, when the shit hits the fan some guys run and some guys stay. Here's Charlie facing the fire; and there's George hidin' in big Daddy's pocket. And what are you doin'? You're gonna reward George and destroy Charlie.

Trask: Are you finished, Mr. Slade?

Slade: No, I'm just gettin' warmed up. I don't know who went to this place, William Howard Taft, William Jennings Bryan, William Tell -- whoever. Their spirit is dead -- if they ever had one -- it's gone. You're building a rat ship here. A vessel for sea goin' snitches. And if you think your preparing these minnows for manhood you better think again. Because I say you are killing the very spirit this institution proclaims it instills! What a sham. What kind of a show are you guys puttin' on here today. I mean, the only class in this act is sittin' next to me. And I'm here to tell ya this boy's soul is intact. It's non-negotiable. You know how I know? Someone here -- and I'm not gonna say who -- offered to buy it. Only Charlie here wasn't sellin'.

Trask: Sir, you are out of order!

Slade: Outta order? I'll show you outta order! You don't know what outta order is, Mr. Trask! I'd show you but I'm too old; I'm too tired; I'm too fuckin' blind. If I were the man I was five years ago I'd take a FLAME-THROWER to this place! Outta order. Who the hell you think you're talkin' to? I've been around, you know? There was a time I could see. And I have seen boys like these, younger than these, their arms torn out, their legs ripped off. But there isn't nothin' like the sight of an amputated spirit; there is no prosthetic for that. You think you're merely sendin' this splendid foot-soldier back home to Oregon with his tail between his legs, but I say you are executin' his SOUL!! And why?! Because he's not a Baird man! Baird men, ya hurt this boy, you're going to be Baird Bums, the lot of ya. And Harry, Jimmy, Trent, wherever you are out there, FUCK YOU too!

Mr. Trask: Stand down, Mr. Slade!

Slade: I'm not finished! As I came in here, I heard those words, "cradle of leadership." Well, when the bow breaks, the cradle will fall. And it has fallen here; it has fallen. Makers of men; creators of leaders; be careful what kind of leaders you're producin' here. I don't know if Charlie's silence here today is right or wrong. I'm not a judge or jury. But I can tell you this: he won't sell anybody out to buy his future!! And that, my friends, is called integrity! That's called courage! Now that's the stuff leaders should be made of. Now I have come to the crossroads in my life. I always knew what the right path was. Without exception, I knew. But I never took it. You know why? It was too damn hard. Now here's Charlie. He's come to the crossroads. He has chosen a path. It's the right path. It's a path made of principle -- that leads to character. Let him continue on his journey. You hold this boy's future in your hands, committee. It's a valuable future. Believe me. Don't destroy it! Protect it. Embrace it. It's gonna make ya proud one day -- I promise you.

Couldn't agree more. It's anime like Amge mentioned. Has no action, no blood, no gore, no humour.
Hit me like a dead weight. One of the saddest and moving movies I have seen.

The series of events at the end of The Shawshank Redemption... That final pull-back shot of Andy and Red hugging each other on the beach in Mexico... it's fucking unbelievable and levels me everytime I watch it.

They just played it yet again this evening. I'm really starting to hate cartoon network for playing it so often, I can't help tearing up and getting morose.

Al Pacino's speech near the end of Scent of a woman. Powerful and moving, it is truly a cinematic moment.

i like the sunrise in lawrence of arabia

maybe not the best, but pretty cool nonetheless


or the plastic bag in american beauty

that's amazing stuff (yeah, right)

I've seen this movie, it's pretty funny. A bit too much fart-joke-type humour though.

I was going to say that ;)
Sadly enough, that was the first thing that came to mind.
