She was known for her headstrong independence, spirited personality, and outspokenness, cultivating a screen persona that matched this public image, and regularly playing strong-willed, sophisticated women.
Hepburn masterminded her comeback, buying out her contract with RKO Radio Pictures and acquiring the film rights to The Philadelphia Story, which she sold on the condition that she be the star.
With her unconventional lifestyle and the independent characters she brought to the screen, Hepburn came to epitomize the "modern woman" in 20th-century America and influenced changing popular perceptions of women.
[11] Thomas Hepburn was eager for his children to use their minds and bodies to the limit and taught them to swim, run, dive, ride, wrestle, and play golf and tennis.
[25] She performed the lead role in a production of The Woman in the Moon in her senior year, and the positive response it received cemented Hepburn's plans to pursue a theatrical career.
"[43] A scout for the Hollywood agent Leland Hayward spotted Hepburn's appearance in The Warrior's Husband, and asked her to test for the part of Sydney Fairfield in the upcoming RKO film A Bill of Divorcement.
"[90] Hepburn's next feature, Stage Door (1937), paired her with Ginger Rogers in a role that mirrored her own life—that of a wealthy society girl trying to make it as an actress.
[94] She was cast in Howard Hawks' screwball comedy Bringing Up Baby (1938), where she played a flighty heiress who loses a leopard while trying to woo a palaeontologist (Cary Grant).
[99] She signed on for the film version of Holiday (1938) with Columbia Pictures, pairing her for the third time with Grant, to play a stifled society girl who finds joy with her sister's fiancé.
[103] Howard Hughes, Hepburn's partner at the time, sensed that the play could be her ticket back to Hollywood stardom and bought her the film rights before it even debuted on stage.
[114][115] Hepburn was also responsible for the development of her next project, the romantic comedy Woman of the Year about a political columnist and a sports reporter whose relationship is threatened by her self-centered independence.
[133] Her next film role came unexpectedly, as she agreed to replace Claudette Colbert only days before shooting began on Frank Capra's political drama State of the Union (1948).
She played Rose Sayer, a prim missionary living in German East Africa at the outbreak of World War I. Co-starring Humphrey Bogart, The African Queen was shot mostly on location in the Belgian Congo, an opportunity Hepburn embraced.
[154] Hepburn subsequently tried to get the play adapted into a film: a script was written by Preston Sturges, and she offered to work for nothing and pay the director herself, but no studio picked up the project.
[166] After two years away from the screen, Hepburn starred in a film adaptation of Tennessee Williams' controversial play Suddenly, Last Summer (1959) with Elizabeth Taylor and Montgomery Clift.
[187] The movie was nominated in all the major categories at the 41st Academy Awards, and for the second year running Hepburn won the Oscar for Best Actress (shared with Barbra Streisand for Funny Girl).
[199] Hepburn received an Emmy Award nomination for playing wistful Southern mother Amanda Wingfield, which opened her mind to future work on the small screen.
Echoing her African Queen character, Hepburn played a deeply religious unmarried woman who teams up with a masculine loner to avenge a family member's death.
[224] The majority of Hepburn's roles from this point were in television movies, which did not receive the critical praise of her earlier work in the medium, but remained popular with audiences.
[226] She received an Emmy nomination for 1986's Mrs. Delafield Wants to Marry, then two years later returned for the comedy Laura Lansing Slept Here, which allowed her to act with her grandniece, Schuyler Grant.
In 1994, she worked opposite Anthony Quinn in This Can't Be Love, which was largely based on Hepburn's own life, with numerous references to her personality and career.
[259] Hepburn often expressed her gratitude toward Smith for his financial and moral support in the early days of her career, and in her autobiography she called herself "a terrible pig" for exploiting his love.
[277][282] Tracy suffered from a severe alcohol addiction and was extremely moody and frequently depressed; Hepburn described him as "tortured",[283] and she devoted herself to making his life easier.
[311] Garson Kanin described what he called "the formula for a Hepburn success: A high-class, or stuck-up ... girl is brought down to earth by an earthy type, or a lowbrow ... or a cataclysmic situation.
[314] Film critic Molly Haskell has commented on the importance of this to Hepburn's career: With an intimidating presence, it was necessary that her characters "do some kind of self-abasement, to stay on the good side of the audience".
[320] Regarding Hepburn's film legacy, one of her biographers, Sheridan Morley, said she "broke the mould" for women in Hollywood,[321] where she brought a new breed of strong-willed females to the screen.
[235] Film academic Andrew Britton wrote a monograph studying Hepburn's "key presence within classical Hollywood, a consistent, potentially radical disturbance",[314] and pinpoints her "central" influence in bringing feminist issues to the screen.
"[177] Mary McNamara, an entertainment journalist and reviewer for the Los Angeles Times wrote, "More than a movie star, Katharine Hepburn was the patron saint of the independent American female.
