Cry might be too strong a word (I'm sure there was smoke in the room) but the following always, er, move me (no, just dust in my eye..., really!):
1 To Kill A Mockingbird
When Atticus shots the mad dog - just the look of admiration in Jem's eye. And, of course, when they all stand up in court for Atticus.

When they move away from Ed Begley's Juror 10 in digust after his rant reveals his bigotry
3 Butch Cassidy and the Sundance Kid
"For a moment there, I thought we were in trouble"
4 The Man Who Would Be King
The look on Connery/Dravot's face after draining his whisky tumbler before signing the contrack. Connery/Dravot's nation building speech.
5 Ordinary People
Quite rightly beat Raging Bull for Best Picture. There, I've said it!

8 Stand By Me
"No, Ace, just you..."
9 Running On Empty

10 Dead Poets' Society

11 The Prince Of Tides

12 Reality Bites

13 Smoke
Auggie's Christmas story
14 The Kite Runner
Reading Hassan's letter - oy, this keeps getting me!
Erm, there's rather too many here!
