Andrews is a former child actress and singer who made her Broadway debut in a 1954 production of The Boy Friend, and rose to prominence starring in musicals such as My Fair Lady and Camelot, both of which earned her Tony Award nominations. In 1957, she made her television debut with the title role in Cinderella, which was seen by over 100 million viewers.

Andrews made her feature film debut in Mary Poppins (1964), for which she won the Academy Award for Best Actress. She received her second Academy Award nomination for The Sound of Music (1965). Adjusted for inflation, these two films are the 25th and 3rd highest grossing films of all time, respectively.

Audrey Hepburn (born Audrey Kathleen Ruston; 4 May 1929 – 20 January 1993) was a British actress and humanitarian. Although modest about her acting ability, Hepburn remains one of the world's most famous actresses of all time who was ranked as the third greatest female screen legend in the history of American cinema. Remembered as both a film and fashion icon of the twentieth century, Hepburn redefined glamour with "elfin" features and a gamine waif-like figure that inspired designs by Givenchy and earned her place in the International Best Dressed List Hall of Fame.

Born in Ixelles, a district of Brussels, Hepburn spent her childhood between Belgium, England and the Netherlands, including German-occupied Arnhem during the Second World War, where she studied ballet with Sonia Gaskell in Amsterdam before moving to London in 1948 to continue ballet training with Marie Rambert and perform as a chorus girl in West End musical theatre productions.

After appearing in several British films and starring in the 1951 Broadway play Gigi, Hepburn gained instant Hollywood stardom for playing the Academy Award-winning lead role in Roman Holiday (1953). Later performing in Sabrina (1954), The Nun's Story (1959), Breakfast at Tiffany's (1961), Charade (1963), My Fair Lady (1964) and Wait Until Dark (1967), Hepburn became one of the great screen actresses of Hollywood's Golden Age who received Academy Award, Golden Globe and BAFTA nominations and accrued a Tony Award for her theatrical performance in the 1954 Broadway play Ondine. Hepburn remains one of few people who have won Academy, Emmy, Grammy, and Tony Awards.

James David Graham Niven (1 March 1910 – 29 July 1983), was a British actor and novelist, best known for his roles as Phileas Fogg in Around the World in 80 Days and Sir Charles Lytton, a.k.a. "the Phantom", in The Pink Panther. He was awarded the 1958 Academy Award for Best Actor in Separate Tables.

Born in London, Niven attended Heatherdown and Stowe before gaining a place at Royal Military College at Sandhurst. He was gazetted a Lieutenant in the Highland Light Infantry. Having developed an interest in acting, he left the Highland Light Infantry, travelled to Hollywood and had several minor roles in film. He first appeared as an extra in the British film There Goes the Bride (1932). From there, he hired an agent and had several small parts in films from 1933, 1934 and 1935, including a non-speaking part in MGM's Mutiny on the Bounty. This brought him to wider attention within the film industry and he was spotted by Samuel Goldwyn. Upon the outbreak of the Second World War, Niven returned to England, and rejoined the army and was recommissioned as a lieutenant.
