Yes, it was a rather funny (yet subtle) goof on the Mormons. Mel Brooks is a comedic genius.
Usually Hollywood has Italians play Indians; my father refers to them as “Wopahoe’s”. Iron Eyes Cody was the most famous, he was Mr. Indian with the single tear shed for the earth in a famous commercial. His parentage was Sicilian.
You may recall a scene from “True Romance” with Dennis Hopper and Christopher Walkin............
Wopahoe’s, LOL! I didn’t know the word, Schwartzers was an Indian word.
