Alternate Character Interpretation: Was Rhodes a basically decent guy beaten down by life who was corrupted by fame and power? Or was he always a horrible person with some nice impulses whose real character was brought out when he got a platform to express it? There's evidence for both.
Big Lipped Alligator Moment: The montage showing the interconnected rise in popularity of Lonesome Rhodes and Vitajex is done in an odd impressionistic style, complete with singing and animation, in contrast to the more naturalistic tone of the rest of the film
Jerkass Woobie: From what little we learn of Lonesome's background, it's clear he had a rotten life up until he became famous.
Retroactive Recognition: As Andy Griffith's name became famous, a film of him mocking the very same warm, household stars he played as became quite notable.
Values Resonance: Let's just say the concept of a narcissist using mass media to manipulate the public never really went away after 1957.
