A plastic surgery fiasco, a mishap at the Academy Awards, stirrings about a possible affair with her husband’s teenage son: by the time she was cast as the simple-minded, unfashionable Ado Annie in Fred Zinnemann’s massive screen adaptation of Oklahoma!, Grahame’s public image was battered. Not a trained singer, she gave the role an awkward hesitancy miles away from the commanding presence of her femme fatales, but entirely appropriate to her farm girl worked over by baffling new passions. In a film full of wide, graceful gestures and panoramic visual effects, her clumsy performance of “I Can’t Say No” strikes the surest emotional note.
