In this guidance, Brian Cutler advises actors to avoid giving unsolicited notes to fellow actors, as doing so may interfere with the director’s and writer’s intended vision. He emphasizes the importance of professionalism on set, suggesting that actors refrain from arguments or confrontations regarding character portrayal. If another actor wishes to discuss changes, Cutler recommends redirecting the conversation to the director, reinforcing a respectful, collaborative approach that honors the original creative direction.
