Saving Private Ryan 

In the World War II saga Saving Private Ryan, Matt Damon, who plays the titular character, is reminiscing about an old story with his brothers, all of whom have been killed at the beginning of the movie. His tale of growing up in a small town with a close-knit family adds some real heart to his character, who we aren’t sure deserves to have a special mission devoted to saving him.

Apparently, Damon improvised this entire scene. There was zero script, but Damon was just super into character, which is how the line ‘picture a girl who took a nosedive from the ugly tree’ managed to pop out of his mouth.
