I think I've heard of instances on TV shows and maybe even movies where actors who don't have any creative duties like writing or directing suggest ideas that get used. I can't think of any examples off-hand (maybe I will after I go to sleep and wake up), but I wonder if there's a clause in the contracts of non-writers preventing them from getting paid if they suggest ideas.
Hmmm, I didn't word this in the form of a question, so... Do non-writers get paid if they suggest ideas to the writers/producers/whoever and those ideas get used while the non-writers don't actually write them or get any special credit?
