SUNDAY PROFILE: 
Thank heaven for Leslie Caron
She began her career as a ballet dancer, but Leslie Caron’s life changed forever when Gene Kelly saw her perform, and cast her in “An American in Paris.” Caron went on to dance opposite Fred Astaire in “Daddy Long Legs,” and became a sensation opposite Maurice Chevalier and Louis Jourdan in “Gigi.” “An American in Paris” is now a hit on the Broadway stage, where our Jane Pauley went recently for an intimate chat with the film legend. (This story was originally broadcast on January 17, 2016.)
