Gildersleeve on Broadway was the third in a series of RKO B-pictures inspired by the radio sitcom The Great Gildersleeve. Harold Peary once more stars as Throckmorton P. Gildersleeve, water commissioner and resident blowhard of the town of Springfield. In this one, Gildy accompanies his pharamacist friend Peavey (Richard LeGrand) at a druggist's convention in New York. Here he becomes romantically involved with wealthy widow Mrs. Chandler (Billie Burke) and brassy gold-digger Francine Gray (Claire Carleton). He also spends his time dodging the arrows of a nut named Homer (Hobart Cavanaugh), who thinks he's cupid. Things get sillier and sillier before the film's slapstick setpiece, which finds Gildy teetering on the edge of a skyscraper. Midget actor Walter Tetley, who played Gildersleeve's nephew Leroy on radio, shows up in a bit role as a bellboy in Gildersleeve on Broadway.
