Breakfast at Tiffany's (film) made capturing the scene a challenge. However, another report claims that the sequence was captured rather quickly due to the good fortune of an unexpected traffic lull. During the film, Hepburn sang the film's signature song, "Moon River" by Henry Mancini and Johnny Mercer. The song was tailored to Hepburn's limited vocal range, based on songs she had performed in 1957's "Funny Face". On the Anniversary Edition DVD of "Breakfast at Tiffany's" co-producer Richard Shepherd says in his audio commentary that after a preview in San Francisco, Martin Rankin, Paramount's head of production, wanted "Moon River" replaced with music by
Audrey Hepburn part because producer Jack L. Warner thought Hepburn or Elizabeth Taylor were more "bankable" propositions. Hepburn initially asked Warner to give the role to Andrews but was eventually cast. Further friction was created when, although non-singer Hepburn had sung in "Funny Face" and had lengthy vocal preparation for the role in "My Fair Lady", her vocals were dubbed by Marni Nixon, whose voice was considered more suitable to the role. Hepburn was initially upset and walked off the set when informed. The press further played up the fabricated rivalry between Hepburn and Andrews, when the latter won an Academy Award
