The tune to which the "Two Princesses" is sung to is a variation of the melody from the Elizabethan traditional song of "Rose Red".
The character "Ahamo - The Seeker" explains he is originally from Nebraska. The name "Ahamo" spelled backwards is "Omaha", the largest city in Nebraska. Also, in the 1939 movie, the Wizard had come to Oz from Omaha.
The main character is named D.G. This stands for Dorothy Gale, the original name of Dorothy in the L. Frank Baum books.
Tin Man broke Sci-Fi's records by being the highest-rated television event in the network's history.
Near the beginning of Part 2, DG affectionately calls her father, "Popsicle" (derived from the more common "pop" or "papa"). This is the same name by which Glinda the Good Witch addresses her father in the salutation of a letter home early in "Wicked," a Broadway musical popular at the time of Tin Man's production and also set in Land of Oz.
Not counting DG, only four characters are referred to on screen by the same (or similar) names to their analogous characters in the original book and 1939 film: Toto, Police Officer Gulch (a reference to Miss Gulch, a character in the 1939 film), The Grey Gale, and Wyatt Cain. Cain is called "tin man" several times by other characters, most notably Glitch when Glitch says "have a heart, tin man"
Glitch makes a reference to not liking scarecrows, a reference to that character's original version.
DG's house number is shown as "39" which references the year _The Wizard of Oz (1939)_ film was released: 1939.
