I came back from a brainstorming/editing session with a fellow writing friend, and he gave me some food for thought on writing characters in scripts. I'm very unfamiliar with script writing, and would like your thoughts. Bear in mind this is for a movie screenplay, not a play's script. Before, I was told that I should be hyper-descriptive, and reveal the character's personality entirely through action. Ex: Jon, a tall white man in his early twenties wearing a tank top and Rayban sunglasses, stares around the room, his face deadpan. From what I understood, my friend was suggesting more along the lines of: Jon (aggressive, egotistic) and dressed in shabby clothing, stares around the room expressionlessly. He thought that this would convey more of who my character actually is to director's and the actor, and not get me bogged up in tiny details that a director might not like, while still maintaining who my character really is. Thoughts?
