She grew up with the nickname Carly Jane by her family and close friends.
She is one of six actresses who have danced with both Fred Astaire and Gene Kelly.
She was discovered by Gene Kelly.
She has said, "Even now I feel furious with myself because whenever there's a camera pointed towards me my MGM training makes me smile. I don't like it. You can see it on all the people who came from that era because there was no question of them not smiling for the camera. Even Katharine Hepburn -- and God knows she was a dramatic actress -- if the camera is on her she smiles."
She and her daughter co-starred on an episode of "The Love Boat", in the parts of mother and daughter, both con artists, engaged in fleecing millionaires.
