Too many to name!
Godfather 2 - I love learning how Vito came to be the Don. I realize that's not just one scene, oh well!
Snoopy - totally agree, the part in Field of Dreams where he gets to play catch with his Dad, gets me everytime! Not to mention his dad is hot!!
Legends of the Fall - I love when Tristan meets Susanah for the first time. Also the scene on the way home when Isabella 2 is shot, my heart just breaks! Or when you see Col. Ludlow for the first time after his stroke.
Braveheart - When Princess Isabelle touches her stomach and you realize that she is pregnant with William Wallaces baby.
Good Will Hunting - When Will finally leaves - to go see about a girl.
Pretty Woman - love when she gets to go shopping
Tombstone - love when they arrive into town.
Dumbo - I love when Dumbo's mom rocks him from inside the jail.
The Wedding Planner - love when Mary gets a little tipsy and Steve takes care of her.
ok - that's enough, I'm sure I could think of a million more.
