The film gives the impression that Toscanini did not give interviews. Toscanini was never interviewed on radio or television, but author and critic B.H. Haggin, who became a personal friend, was the only critic allowed access to the conductor and visited him often, resulting in a book entitled "Conversations with Toscanini", published after the conductor's death. And NBC Symphony Orchestra member Samuel Antek, who wrote a book entitled "This Was Toscanini", visited him at his home in Riverdale; Antek included this experience in his book.
Martin Bookspan's voice is heard announcing one of the Toscanini telecasts, shown between 1948 and 1952. Bookspan's voice was not heard on the original telecasts; they were originally announced by Ben Grauer, but because of the bad audio quality, they were replaced on the VHS and DVD editions of the Toscanini telecasts by the voice of Martin Bookspan. These VHS and DVD editions were issued more than thirty years after Toscanini's death.
