Errors in geography: In the protest scene outside of the mattress store, protesters set fire in a trash barrel that has the letters D.S.N.Y., presumably for "Department of Sanitation of New York". However, this scene is set in Memphis.
Continuity: The Variety cover announcing Lonesome Rhodes on-air meltdown not only mis-spells his last name as "Roads" but is also dated "November 21, 1956" which is well before the other dates in the movie, for example, earlier he was picking Miss Arkansas Twirler 1957.
Continuity: When introducing his new bride, Lonesome's jacket goes from being buttoned to being open and back to being buttoned again.
Errors made by characters (possibly deliberate errors by the filmmakers): When Rhodes introduces Betty Lou and her flaming baton routine, he identifies the music as being from Beethoven's 7th symphony. The piece is actually from Beethoven's 9th.
