Bringing Up Baby is a 1938 American screwball comedy film starring Katharine Hepburn and Cary Grant. The film tells the story of a paleontologist in a number of predicaments involving a scatterbrained heiress and a leopard named ‘Baby’. The screenplay was adapted by Dudley Nichols and Hagar Wilde from a short story by Wilde which originally appeared in Collier's Weekly magazine on 10 April 1937. The script was written specifically for Hepburn and was tailored to her personality. Filming began in September 1937 and wrapped in January 1938 over schedule and over budget. Production was frequently delayed due to uncontrollable laughing fits between Hepburn and Grant. A tame leopard was used during the shooting; its trainer was off-screen with a whip for all its scenes.
