The portrayal of Holly Golightly as the naive, eccentric socialite is generally considered to be Audrey Hepburn’s most memorable and identifiable role. She herself regarded it as one of her most challenging roles to play, as she was an introvert who had to play an extrovert. Hepburn’s singing of “Moon River” helped garner an Oscar for Best Song for composer Henry Mancini and lyricist Johnny Mercer. The film also featured what was arguably George Peppard’s greatest acting role and the high point of his career. The film is based on the novella of the same name by Truman Capote.
