The cast will share secrets from the set, reminiscences about their time together, and what their lives have been like in the years since the movie was released.
In addition, the von Trapp Children -- a singing group featuring members of the real von Trapp family -- will pay their own special tribute to the film that made their family name known throughout the world.
The 1965 film is based on the classic Rodgers and Hammerstein stage musical. It won five Academy Awards, including Best Picture. A special edition of the film will be released on DVD and Blu-Ray on November 2.
