Rhythm and Length
Excerpted from an article in The Nation about Joan Didion:
In Blue Nights, her 2011 memoir about grief, family, and work, Didion said that when she and her husband, John Gregory Dunne, worked on dialogue for their screenplays, they would mark the time a character spent speaking before coming up with the words themselves: What was said was not as important as the rhythm and length of the speech.
That’s interesting. That sounds more like a song than a screenplay.
