Character Analysis
Johnny Fontane is a singer, loosely based on Frank Sinatra. He wants to get a part in a hit movie, graduating from famous crooner to mega-celebrity (kind of like Sinatra did with From Here to Eternity).
But Jack Woltz, the producer, blackballs Fontane because he's still miffed at him for seducing his female protégé. Fortunately for Fontane, a severed horse head manages, super grotesquely, to secure the role.
Al Martino plays the role.
