Born Yesterday is a 1950 American comedy-drama film directed by George Cukor, based on the 1946 stage play of the same name by Garson Kanin. The screenplay was credited to Albert Mannheimer. According to Kanin's autobiography, Cukor did not like Mannheimer's work, believing it lacked much of the play's value, so he approached Kanin about adapting a screenplay from his own play. Because of legal entanglements, Kanin did not receive screen credit.

George Dewey Cukor was an American film director and producer. He mainly concentrated on comedies and literary adaptations. His career flourished at RKO when David O. Selznick, the studio's Head of Production, assigned Cukor to direct several of RKO's major films, including What Price Hollywood? (1932), A Bill of Divorcement (1932), Our Betters (1933), and Little Women (1933). When Selznick moved to Metro-Goldwyn-Mayer in 1933, Cukor followed and directed Dinner at Eight (1933) and David Copperfield (1935) for Selznick, and Romeo and Juliet (1936) and Camille (1936) for Irving Thalberg.
