The Lionsgate DVD contains a 35 minute short from the Island Film Group, "Kaiulani: Crown Princess of Hawaii", directed by Roy Tjioe. The short (which reproduces the New York Harbor speech) gives much more detailed history, including the conviction of the Queen and pardon for treason, and the visits of novelist Robert Louis Stevenson. The political and legal process of annexation to the United States is discussed. The medical causes of her death are explained.
"The native peoples were plundered by people who wanted more." This was America's first forced regime change. Ironically, I just got a book by George Friedman "The Next Decade" that maintains America has an unintended or accidental empire that threatens the nature of its Republic.
The music soundtrack (including that of the featurette) includes some uncredited piano music that sounds like a Chopin nocturne. The original music is by Stephen Warbeck and the Honolulu Symphony is used, and it plays quite well.
