Stage charm guarantees in advance an actor's hold on the audience, it helps him to carry over to large numbers of people his creative purposes. It enhances his roles and his art. Yet it is of utmost importance that he use this precious gift with prudence, wisdom, and modesty. It is a great shame when he does not realize this and goes on to exploit, to play on his ability to charm.
