On the back of a poster

"I read a fencing on this issue: Does the actor serve the writer, or does the writer serve the actor? And how easy it is to judge: If the actor is greater in art than the writer (in the art of writing), then the writer serves. And vice versa. Otherwise, the judgment can be made play by play, if we take the text after the play and look at it: - What has the writer given the actor? - What has the actor made out of it?"
