In the mid ’90s I attended a lecture about screenwriting by the great Robert Towne (Chinatown, The Last Detail, The Firm), and I remember his stressing the importance of being able to weave refrains into a script. He was referring to a line or a thought or an offhanded remark that is used or understood in one particular way early on, and then is used again in Act Two or Three in a way that adds to the first meaning and perhaps even doubles back and reverses it in some way. Most HE readers know what I’m talking about, and I’m trying to think of examples of refrain used in any mainstream films over the last….oh, five years or so.
