25. AUDREY HEPBURN
My Fair Lady (1964)
Audrey Hepburn bespeaks a plucky elegance that permeates her turn from a ''draggle-tail guttersnipe'' into a proper English aristocrat. But it was her singing that turned out to be problematic at Oscar time: Eliza's numbers were voiced by Marni Nixon (West Side Story). Resentment also lingered that studio head Jack Warner had given Hepburn the part over the untested Julie Andrews. Come ceremony time, Andrews took the Oscar for Mary Poppins, but Hepburn received a long ovation, proving she still won plenty of hearts.
