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