Brevity and subtext, attention to role and history of character, and careful attention to rhythm and tempo (must feel real but actually be sublimely constructed). Wonderful direction, thank you. I suspect the character we give our voice to is the easiest, but the others, I want their histories and varied lives to be implicit in their speech and topics of speech, and those are the ones I need to approach extra smartly. I acted once, in a high school play, Mayella Ewell in To Kill a Mockingbird, it was hugely instructional, learning to drop into and inhabit someone else. The very small bit of dialogue I've written, and that met with positive response from a pro, was devised this way, inhabiting each character to write their lines, and it sounds like that's actually a decent way to proceed with dialogue in general. Thank you so much, Scott!
