#7-Be observant.
I watched a documentary about the Coen brothers recently. Peter Stormare (Grimsrud in Fargo) said his line was, "Let's go to the Pancakes House." He thought it was an error--should've been written "Pancake," singular. When he made the correction, one of the brothers came over and quietly said, "No, no. I heard this guy call it the Pancakes House." Perhaps a tiny detail, but hundreds of tiny, real details from daily observations can make a deeper character, a richer scene and a great script.
