I have been approached by an actor with a great idea for a series to write the pilot. It's his idea, and sure I'll bring something to it too. How do I recognize and protect the interests of the person who came up with the idea? Do I list him in the title page of the script with CONCEPT BY XXXXX, WRITTEN BY YYYYY. Or do I list him as a co-writer? And is listing this person on the cover page the best way to do this? I'm looking to the experience on Stage 32 to come to the rescue.
