Nope. Films acknowledge a difference between the writers, the book that inspired it, and the director.
Pretending that your model use doesn't matter, is ignoring all the people's works that are being used to construct it.
If one director or producer went around bragging that the film was all their work, the Actor's Unions and Writer's Unions would tear them to pieces.
You can't pretend only you are the creator. Because it does matter.
