Description of Lonesome Rhodes, the leading character from the film, A Face in the Crowd:
Andy Griffith makes a spectacular film debut as Lonesome Rhodes, a philosophical country-western singer discovered in a tanktown jail by television talent coordinator Patricia Neal and her assistant Walter Matthau. They decide that Rhodes is worthy of a TV guest spot, the result being that the gangly, aw-shucks entertainer becomes an overnight sensation. As he ascends to stardom, Rhodes attracts fans, sponsors and endorsements by the carload, and soon he is the most powerful and influential entertainer on the airwaves. Beloved by his audience, Rhodes reveals himself to his intimates as a scheming, power-hungry manipulator, with Machiavellian political aspirations. He uses everyone around him, coldly discarding anyone who might impede his climb to the top (one such victim is sexy baton-twirler Lee Remick, likewise making her film debut). Just when it seems that there's no stopping Rhodes' megalomania, his mentor and ex-lover Neal exposes this Idol of Millions as the rat that he is.
