The wiki site TV Tropes, in its infinite nomenclatural wisdom, has created a term for films or TV shows in which the protagonist’s first name is also the name of the lead actor: the Danza (after Tony Danza, who played a guy named Tony in two long-running sitcoms, Taxi and Who’s the Boss?). There are many reasons to pull a Danza, but the most important has to do with name recognition as brand leverage. Some performers, especially stand-up comedians (think Louis C.K. or Roseanne Barr), are so identified with their names that basing a character on their stage persona and then giving that character a different name just seems like a needless waste of ready-to-hand audience goodwill.
