Okay, I admit it: My first post (#3 or so) was a trap meant to entice CapMandrake into participating in this survey.
For great scenes (not just lines, as my first post suggested) in a movie, how about when "Boy" returns to his home in the Shenandoah Valley after being mistaken for a Confederate soldier and taken prisoner. The remnant of his family, which has suffered immensely in the war, is gathered in church that morning. The Boy walks into the church, the service suddenly halts as they see him, and then the congregation begins singing the Doxology ("Praise God from whom all blessings flow...") as the Boy hobbles up the aisle on his crutch to his father's side.
The movie is Shenandoah with Jimmy Stewart.
That film is one of my Father's favorites!
How about the river crossing of the 82nd to capture Niimegen Brigade in Bridge Too Far? "Hail Mary!" That location is one of the 'must see during my life' spots for me.
