Guy Rennie graduated from the University of Iowa where he studied acting. His first job was radio broadcaster in Philadelphia. He traveled to Morocco where he gained fame as a singer and comedian. In the 1930's he co-starred with singer Josephine Baker at the Parisian club "Les Ambassadeurs." He eventually opened his own nightclub in Paris.

He eventually returned to the US to star at Manhattan's Weylan Hotel. In 1946, he moved to Miami Beach, which became his permanent home. He acted in films and TV shows in Los Angeles, where he maintained a second home.
