I recently finished up writing a short screenplay. The screenplay is an adaption from a short story written by someone I don't know.
Right now, I have the credit as "Written by Lee Stokes, adapted from a Story by Book Writer".
Which if it was a straight forward adaptation, I would move ahead with.
HOWEVER, the truth is that as I wrote the screenplay, I realized that I hated the ending in the book.
I liked the characters, the setup, and most of the story, but when the payoff came, I pretty much hated it.
As the screenplay is now, I'd say like 2/3 or 3/4 of the story is the authors, but the final piece is wholly mine. I mean, my ending is nothing like his, nor based in any way on his original ending.
So two questions:
1. how do I credit the writing?
2. how do I broach the situation to the author when the time comes to try to obtain rights?
Any thoughts, insights or tips appreciated. If whatever I wrote isn't clear, I am willing to try and explain further.
