All these producers have to do is give me a call. I'd be pleased to edit their scripts, and story boards, to prevent such errors. If they pay for my first class plane fare, and a five star hotel, I'd also be willing to attend all rehearsals, as well as the final production, and edit.
All I would expect in return would be my consulting fee of $1000.00 an hour, and my own trailer on the production lot, with M & M candy, with all the green M & M's removed.
