Oscar-worthy Movie: Mogambo (1953)

Honey Bear. We're not stupid enough to give Gardner an adorable nickname. No, "Honey Bear" Kelly is the role that earned Gardner her Academy Award nomination.

In Mogambo, Kelly navigates African terrain, beats Grace Kelly to get the man (Clark Gable), and swims upriver just to accept his proposal. She embodied charisma and beauty, all while playing with a baby elephant. And yet, the woman named by the American Film Institute as one of the "greatest female stars" never got an Oscar trophy to prove it—not even the honorary kind.
