The Life of Riley in its best-known version evolved from a prospective Groucho Marx vehicle called The Flotsam Family. The Marx series failed at audition when the would-be sponsor wouldn't accept Groucho in what was, for him, a straight role--as head of a family. Then producer Irving Brecher saw a film, The McGuerins of Brooklyn, with a rugged-looking and typically American blue-collar man, William Bendix, in one of the leading roles. There, on the screen, was his character. A new audition was recorded, with Bendix as star and the character renamed Chester A. Riley. It became a solid midlevel hit.
