Conversation so far:
What was the revelation that shaped Lee Strasberg's life?
H]e observed, first of all, that all the actors, whether they were playing leads or small parts, worked with the same commitment and intensity.
Where did he observe the actors?
when Stanislavski brought his Moscow Art Theatre to the United States in 1923.
What was unique about these actors?
More important, every actor seemed to project some sort of unspoken, yet palpable, inner life for his or her character.
Did he learn anything from their acting style?
he could be mentally prepared by resort to analogous mental exercises.
They worked on relaxation as well as concentration.
What did he do after this following with the Art Theater?
Strasberg eventually left the Clare Tree Major School to study with students of Stanislavski - Maria Ouspenskaya and Richard Boleslavsky - at the American Laboratory Theatre.
Did he perform or direct anything while there?
In 1925, Strasberg had his first professional appearance in Processional, a play produced by the Theater Guild.

Question: Is there anything else that is interesting?
Self-contained rewrite: Is there anything else that is interesting about Lee Strasberg aside from his work with the American Labaoratory Theatre or the following of the Moscos Art Theatre??
