How Dialogue Is Like Toilet Paper by William C. Martell
Some interesting questions and answers about writing dialogue for your screenplay. I find it helpful to know the characters as much as possible so that the dialogue flows. A lot of work is done in character development and backstory so that I can achieve this process...but sometimes that doesn't work. Sometimes the process is much more fluid and it comes from the exchange between the characters and scene...and sometimes you don't need it because of subtext...in which case dialogue is pointless and useless. But then again, I love the way Quentin Tarantino uses mundane situations to heighten character exposition.
