Annette Bening had the rare opportunity to meet with actress Terry Moore, an old friend of Gloria Grahame who played her stepmother in Man on a Tightrope (1953). Moore and Grahame had both attended the Academy Awards on the night Moore was nominated for Come Back, Little Sheba (1952) and Grahame won for The Bad and the Beautiful (1952). Annette was able to learn that Grahame was quite a private person who'd never discuss her husband or family life in general. She was also so stubborn that director Elia Kazan only managed to get her to weep for a scene in 'Tightrope' by telling her that co-star Moore was a better actress.
When Gloria Grahame and Peter Turner are sunbathing in Central Park, Gloria suggests they live together. Peter replies "I think I'm just a boy who can't say no." In the 1955 movie Oklahoma! (1955), the real Gloria Grahame, as Ado Annie, sang "I Cain't Say No" where the lyrics includes "I'm Just a Girl Who Cain't Say No" in two places.
