Screenwriting : Writing lines for characters that do not have proper names by George Pierson

I base my dialogues and speech on each characters personality ,

It all depends on how important each character is to the story. Are they major characters good or bad? Does their presence move plot along? Are they there to create romantic tension? Etc. If a character has no proper name but important in story they could have a strong personality trait or that together with action line EG The Mad River Fisherman, the Blood Thirsty Real Estate Lawyer, The Ruthless Local News Reporter Etc or who are they in a particular society such as The Village Elder, The Local Soothsayer, The Town Bike Etc. Don’t forget if they are characters who just pass by on a page maybe don’t give them a name at all. Readers identify with a name and expect to see them again but if a secondary character who only appears once or twice I describe them as how they serve story. EG Vincent ran up to the street florist to grab a bunch of red roses. “Ten pounds and I’ll give you a red ribbon too” THE SELLER asked raising his eyebrow. Rather than. JACK looked at Vincent holding up a red ribbon and offered him a good deal etc……Reader then identifies with Jack who is someone who will never appear again whereas it’s best to let reader know straight away who to invest in. Only a small point but important.

Character has dialog? Give it a name (could be gematric - Cab Driver, Lawyer, Policeman.,,) - or specific if it's a character tied to the story line. It becomes important when we run production reports. Just do it.

What did they do with unnamed characters in the couple of dozen screenplays that you read before you attempted to write one?

Just do the same.

I give the characters evocative names based on their characteristics/roles, some recent ones being: RED-CHEEKED PATRON and GUMBEATER.

Doug Nelson, I think that your suggestion might work the best for what I need. Thank you everybody for your input, I do appreciate it.
