One screen and one movie is being played.
3 sets of people are watching the same movie.
First comes the *Audience*. while watching the movie they are getting carried away with the different emotions played by the different roles. They admirethe hero, laugh with the comedian and hate the villain’s character.
They are involved in the story so much that they forget they are just the spectators here.
Then there are *actors* who acted in that movie are watching the same screen and they are well aware that all the characters on the screen are acting as per the roles assigned to them. Here every actor is focusing more on their acting ability and they are learning how best they can improve and prepare for upcoming opportunities to prove themselves the best.
Then comes the *Director* . His focus is on how best he can present the story on screen by making every actor play their role best. As every character in his story is important to him.
While watching the movie he is sitting there as a silent witness to his own play by not being judgmental about any character.
