For the first time in its 75-year history, the Actors Studio, where generations of actors have studied the art of performing, has opened its doors to outside cameras to capture a session where members hone their craft. Ben Mankiewicz, host of Turner Classic Movies, talks with Studio co-presidents and Oscar winners Ellen Burstyn and Al Pacino, members Carol Kane and Justin Marcel McManus, and author Isaac Butler about the past, present and future of the acclaimed training ground and the acting community that has revolutionized the business.
