Lana Wachowski (formerly Laurence "Larry" Wachowski, born June 21, 1965) and Lilly Wachowski (formerly Andrew Paul "Andy" Wachowski, born December 29, 1967) are American film directors, screenwriters, and producers.  They are siblings, and are both trans women.  Collectively known as The Wachowskis ( ) and formerly as The Wachowski Brothers, the pair made their directing debut in 1996 with "Bound", and achieved fame with their second film "The Matrix" (1999), a major box office success for which they won the Saturn Award for Best Director.  They wrote and directed its two sequels: "The Matrix Reloaded" and "The Matrix Revolutions" (both in 2003), and were deeply involved in the writing and production of other works in that franchise. An Actor Prepares (Russian: "Работа актера над собой" ) is the first of Konstantin Stanislavski's books on acting, followed by "Building a Character" and "Creating a Role".  Stanislavski intended to publish the contents of "An Actor Prepares" and "Building a Character" as a single volume, and in the Russian language.  However, "An Actor Prepares" was first published as a single volume in English, and World War II delayed the publication of "Building a Character" for more than ten years. The "art of representation" (Russian: "predstavlenie" ) is a critical term used by the seminal Russian theatre practitioner Konstantin Stanislavski to describe a method of acting.  It comes from his acting manual "An Actor Prepares" (1936).  Stanislavski defines his own approach to acting as "experiencing the role" and contrasts it with the "art of representation".  It is on the basis of this formulation that the American Method acting teacher Uta Hagen defines her recommended Stanislavskian approach as 'presentational' acting, as opposed to 'representational' acting.  This use, however, directly contradicts mainstream critical use of these terms.  Despite the distinction, Stanislavskian theatre, in which actors 'experience' their roles, remains 'representational' in the broader critical sense. Method acting is a range of training and rehearsal techniques that seek to encourage sincere and emotionally expressive performances, as formulated by a number of different theatre practitioners, principally in the United States, where it is among the most popular—and controversial—approaches to acting.  These techniques are built on the Stanislavski's "system" of the Russian actor and director Konstantin Stanislavski.  Though many have contributed to the development of the Method, three teachers are associated with "having set the standard of its success", though each emphasized different aspects of the approach: Lee Strasberg (the psychological aspects), Stella Adler (the sociological aspects), and Sanford Meisner (the behavioral aspects).  The approach was first developed when they worked together at the Group Theatre in New York.  All three subsequently claimed to be the rightful heirs of Stanislavski's approach.  His three major books were "An Actor Prepares", "Building a Character", and "Creating a Role".
