"The actor has to develop his body. The actor has to work on his voice. But the most important thing the actor has to work on is his mind"

This quote by Stella Adler highlights the significance of the star's psychological development. She recommends that the actor should not only concentrate on their physical and vocal abilities, but likewise on their mental capability. She believes that the star should work on their mind in order to be successful. This indicates that the actor must have the ability to believe seriously and artistically, and be able to interpret and analyze the text they are carrying out. They should also be able to understand the motivations of their characters and have the ability to bring them to life. In addition, the actor needs to be able to understand the context of the play and the audience they are carrying out for. By establishing their mind, the star can end up being a more effective and successful entertainer.
