Long story short, I've been considering doing some amateur film making, turning my stories into movies. But I still want the stories published. If I turn them into movies and make them publicly available, would a publisher still accept them? I'd like to think so, since movies are not the same as novels, but they'd still be the same stories. Just in a different format. Also, a bonus question just for future reference. If I were to decide to make an amateur film based on someone else's work, would that require permission even though the original author would be named and I would be making zero profit?
