She was born Eleanor Geisman.
She was 5’ 1” tall.
In 1945, Harvard Lampoon voted her worst actress of the year. That year's worst actor was regular co-star Van Johnson.
She was a longtime friend of Esther Williams.
She initially turned down the opportunity to be a celebrity spokesperson for Depends undergarments because "it was not a very pleasant subject". Reportedly, her mother changed her mind because she convinced her that she could actually help people with a very real and widespread problem that they were too embarrassed to talk about with friends or family. (So you see, it all depends.)
She said, “I have big teeth. I lisp. My eyes disappear when I smile. My voice is funny. I don't sing like Judy Garland. I don't dance like Cyd Charisse. But women identify with me. And while men desire Cyd Charisse, they'd take me home to meet Mom.”
