"You can't just go in there and open your mouth until the cast and director feel comfortable with you"

This quote by Beth Henley is a tip to actors to be conscious of their behavior when auditioning for a function. It is essential to be respectful and expert when auditioning, and not to be overly aggressive or pushy. The quote is suggesting that stars should not be too eager to make their existence understood, however rather wait until the cast and director are comfy with them prior to speaking out. This is necessary since it lionizes for the director and cast, and permits them to be familiar with the actor before making any choices. It also enables the actor to get a much better feel for the environment of the audition and the expectations of the director. By being mindful of their behavior, stars can make a much better impression and increase their chances of getting the function.
