Red Skelton's final film starring vehicle is an expansion of an hour-long TV play, which also starred Skelton when it was originally seen in September of 1955 on the weekly anthology Climax!. Skelton plays doltish lunchroom attendant Rusty Morgan, who is dutifully saving up enough money so that he and sweetheart Edith Enders (Janet Blair) can be married. Rusty foolishly entrusts his bankroll to a gang of stock swindlers, whom he believes to be FBI agents. Before long, our hero finds hmself the crooks' unwitting courier, landing in jail as a result. After a zany prison break orchestrated by genuine FBI agents who've had their eyes on Rusty all along, our hero catches up with the crooks during a nightclub floor show presided over by the vivacious Rita DeLacey (Vivian Blaine). Produced by RKO Radio, Public Pigeon No. 1 was eventually released by Universal-International.
