Columbia Masterworks Records by John Gielgud—the longest-running "Hamlet" in Broadway history to date. Columbia Masterworks' most successful Broadway album was the original cast recording of "My Fair Lady" (OL-5090, 1956), starring Rex Harrison, Julie Andrews, Stanley Holloway and Robert Coote. This first album was issued only in mono, but the first stereo recording of "My Fair Lady"—featuring the same four stars, this time with the London cast—followed in 1959. And in 1964, Columbia Masterworks issued the film soundtrack album of the show, starring Rex Harrison and Audrey Hepburn's "singing voice", Marni Nixon. The most successful film soundtrack release on Columbia Masterworks was the
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
