the role of David Huxley. Hawks initially wanted silent-film comedian Harold Lloyd; Berman rejected Lloyd and Ronald Colman, offering the role to Robert Montgomery, Fredric March and Ray Milland (all of whom turned it down). Hawks' friend Howard Hughes finally suggested Cary Grant for the role. Grant had just finished shooting his breakthrough romantic comedy The Awful Truth (1937), and Hawks may have seen a rough cut of the unreleased film. Grant then had a non-exclusive, four-picture deal with RKO for $50,000 per film, and Grant's manager used his casting in the film to renegotiate his contract, earning him $75,000 plus the bonuses Hepburn was receiving. Grant was concerned about being able to play an intellectual character and took two weeks to accept the role, despite the new contract. Hawks built Grant's confidence by promising to coach him throughout the film, instructing him to watch Harold Lloyd films for inspiration. Grant met with Howard Hughes throughout the film to discuss his character, which he said helped his performance. Hawks obtained character actors Charlie Ruggles on loan from Paramount Pictures for Major Horace Applegate and Barry Fitzgerald on loan from The Mary Pickford Corporation to play gardener Aloysius Gogarty. Hawks cast Virginia Walker as Alice Swallow, David's fiancée; Walker was under contract to him and later married his brother William Hawks. As Hawks could not find a panther that would work for the film, Baby was changed to a leopard so they could cast the trained leopard Nissa, who had worked in films for eight years, making several B-movies. Filming Shooting began September 23, 1937, and was scheduled to end November 20, 1937, on a budget of $767,676. Filming began in-studio with the scenes in Susan's apartment, moving to the Bel Air Country Club in early October for the golf-course scenes. The production had a difficult start due to Hepburn's struggles with her character and her comedic abilities. She frequently overacted, trying too hard to be funny, and Hawks asked vaudeville veteran Walter Catlett to help coach her. Catlett acted out scenes with Grant for Hepburn, showing her that he was funnier when he was serious. Hepburn understood, acted naturally and played herself for the rest of the shoot; she was so impressed by Catlett's talent and coaching ability that she insisted he play Constable Slocum in the film. Most shooting was done at the Arthur Ranch in the San Fernando
