I just watched me Barbie movie, which I liked very much. I was struck by how succinctly the dramatic arc of Gerwig and Bombach’s story was encapsulated by the very last line of dialogue in the film.
This is true of other great scripts as well. One obvious example is Robert Towne’s screenplay for Chinatown.
I wonder how many films can be described in this way: The last line of dialogue neatly encapsulates the arc of its hero’s journey.
