A lot of the above, and
LOTR-ROTK, When All of Gondor takes a knee.
I lose it right before that, when Arwen show up, and you read Elrond's lips, and he says "Go to him." She curtsies, and he stops her by the chin, and lays that big ol' kiss on her! By the time they bow to the Hobbits, I'm well on my way to slitting my wrists! :lol
Forrest Gump, at the tree. "He's so smart Jenny!" Everytime . . .
Boondock Saints II Dream sequence, when their buddy who was just shot comes skating up, "Thanks fah cahmin' out!"
The Santa Clause, when everyone gets there gifts.
Elf, when Santa's sleigh sneaks up on the crowd and "A New Hopes" over the heads, and the music cue just nails ya! Bam!
End of
Edward Scissorhands
Whole ending of
Star Trek: Wrath of Khan
Whole opening of
Star Trek that music does it. Even got my girlfreind the first time I got her to watch it!
And I'm probably alone on this one, but at the end of Star Trek IV, when Spock and Sarek have that great exchange, ever so breifly and logically, basically telling each other how much they love each other, and Kirk watches quietly. Ends so perfect with "Tell her, I feel fine."
