The main difference between the art of the actor and all other arts is that every other [non-performing] artist may create whenever he is in the mood of inspiration. But the artist of the stage must be the master of his own inspiration, and must know how to call it forth at the hour announced on the posters of the theatre. This is the chief secret of our art.
Constantin StanislavskiIn spite of my great admiration for individual splendid talents I do not accept the star system. Collective creative effort is the root of our kind of art. That requires ensemble acting and whoever mars that ensemble is committing a crime not only against his comrades but also against the very art of which he is the servant.
Constantin StanislavskiThe actor must use his imagination to be able to answer all questions (when, where, why, how). Make the make-believer existence more definite.
