A movie without flow is like a martini glass without a stem: preposterous. Nathan and Ryan address the importance of screating an elegant flow with deer-like momentum in your screenplay. They break down the sandiness of “Mad Max” (the newer one), Ryan reveals his “Edge of Your Seat” test, and they discuss why screenplay writers should never have standing desks. They plan to do script surgery on Wonder Woman, but it doesn’t need any. Nathan pitches his slam-dunk screenplay concept, “Diva and the Devil.” Ryan agrees to be an equal partner in bringing it to life and in all proceeds from its sale.
