‘I try to make my screenplays as readable an experience as I can…’—William Goldman

I try to make my screenplays as readable an experience as I can, for a good reason and greedy reason— I want the executives, who read them and who have the power to greenlight a flick, to say ‘Hey, I can make money out of this.’

Obvious truism: we all want the movies we write to get made. And that’s only going to happen if someone likes the script. Executives read a guh-zillion scripts a weekend. It would be idiotic for me to not have him try and enjoy the ride.”
