Christened simply Audrey Kathleen Ruston, her mother Baroness Ella Van Heemstra temporarily changed the actress' name from Audrey to Edda during the war, feeling that "Audrey" might indicate her British roots too strongly. During the war, being English in occupied Holland was not an asset; it could have attracted the attention of the occupying German forces and resulted in confinement or even deportation. After the war, her father, Joseph Victor Anthony Ruston, found documents about his ancestors, some of whom bore the name Hepburn. This is when he added it to his name, which caused her daughter to have to legally add Hepburn to her name as well, thus Audrey Kathleen Hepburn-Ruston.

Was fluent in English, Spanish, French, Dutch/Flemish and Italian.

Was briefly considered for the main role in Cleopatra (1963) but the part went to Elizabeth Taylor

She confessed to eating tulip bulbs and tried to bake grass into bread during the hard days of World War II.

Audrey felt that she was miscast as Holly Golightly in Breakfast at Tiffany's (1961) although it was one of her most popular roles.

Was trained as a dental assistant before making it big.

Broke her back during filming of a horse-riding scene in _Unforgiven, The (1960)_

Henry Mancini said of her: "'Moon River' was written for her. No one else had ever understood it so completely. There have been more than a thousand versions of 'Moon River', but hers is inquestionably the greatest".

Turned down a role in the film The Diary of Anne Frank (1959) because, as a young girl in Holland during the war, she had witnessed Nazi soldiers publicly executing people in the streets and herding Jews onto railroad cars to be sent to the death camps. She said that participating in the film would bring back too many painful memories for her.

Like Humphrey Bogart, Hepburn also starred in five of the movies listed by American Film Institute in its Top 100 U.S. love stories (2002). They are Roman Holiday (1953), ranked #4 on the list, Sabrina (1954) ranked #54, which co-starred Bogart, My Fair Lady (1964) ranked #12, Two for the Road (1967) at #57 and Breakfast at Tiffany's (1961) #61.
