After briefly considering Hawks's cousin [[Carole Lombard]] for the role of Susan Vance, producers chose Katharine Hepburn to play the wealthy New Englander because of her background and similarities to the character. RKO agreed to the casting, but had reservations because of Hepburn's salary and lack of box-office success for several years.{{sfn|McCarthy|1997|p=247}} Producer Lou Lusty said, "You couldn't even break even, if a Hepburn show cost eight hundred grand."{{sfn|Mast|1988|p=7}} At first, Hawks and producer [[Pandro S. Berman]] could not agree on whom to cast in 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 (actor)|Robert Montgomery]], [[Fredric March]] and [[Ray Milland]] (all of whom turned it down).{{sfn|Eliot|2004|pp=176–177}}

Hawks' friend [[Howard Hughes]] finally suggested Cary Grant for the role.{{sfn|Eliot|2004|p=174}} Grant had just finished shooting his breakthrough romantic comedy ''[[The Awful Truth]]'' (1937),{{sfn|McCarthy|1997|p=247}} and Hawks may have seen a rough cut of the unreleased film.{{sfn|Mast|1988|p=7}} 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.{{sfn|Eliot|2004|pp=176–177}} 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.{{sfn|Eliot|2004|p=178}} Grant met with Howard Hughes throughout the film to discuss his character, which he said helped his performance.{{sfn|Eliot|2004|p=178}}

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.{{sfn|McCarthy|1997|p=247}} Hawks cast Virginia Walker as Alice Swallow, David's fiancée; Walker was under contract to him and later married his brother [[William Hawks]].{{sfn|McCarthy|1997|p=248}} 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.{{sfn|Mast|1988|p=7}}
