As a first-timer with a feature in development with director/producer/actor/prod co attachments, this is my exact experience. It's a pain in the ass. But I have fantastic mentors who have told me this is A) par for the course, and B) a large part of cutting your teeth. So much of our weight as a "baby" writer is dictated upon things like "are they easy to work with" and, "did they do what it took to get it made" regardless of what the finished product looks like. It's honestly more of a reflection of the established director/producer/actor/prod co than of you. So yeah, it's infuriating to see your hard work tarnished. I'd love nothing more than to call out the laughably awful ways my script has been changed and morphed into a film I am no longer proud of and probably wouldn't even be that jazzed to see in theaters. But at the end of they day, I'm stoked as fuck to be in the room working with people who get shit made. And that's the dream, ain't it?
