off the top of my head:
celie reuniting with her sister
'somewhere out there' in an american tail
when cinderella's crying after her sisters rip her dress and her fairy godmother appears
la misma luna when carlos gets to the meeting place and is waiting for the 'walk' sign to come on
end scene of white heat- MADE IT MA!! TOP OF THE WORLD!!

any movie i've seen in which someone is shot or shoots themself in the head
pulp fiction- *exhale* bring out the gimp
wayne's world- singing to queen
all of trainspotting
all of gone with the wind
and about a billion others i'm missing......
