The filmmakers states that the Duke tobacco trust was dissolved in the 1920's. The Supreme Court decision against American Tobacco was handed down on May 29, 1911.
The filmmaker states that after the dissolution of the American Tobacco Company trust the Duke family diversified into textiles and electric power. In fact, the Duke family had been invested in these enterprises as far back as the late 1800's. The Supreme Court of the United States handed down their decision dissolving the Tobacco trust on May 29, 1911, not in the 1920's as stated in the film.
