Cary and his leading ladies
As I watched this I found myself thinking, it's nice to see Cary Grant with a woman close to his own age for a change. His leading ladies from this era include Leslie Caron, Audrey Hepburn, Doris Day, Deborah Kerr, Eva Marie Saint, Sophia Loren, Suzy Parker, and Grace Kelly. These woman all ranged from 18 to 30 years younger than him.
Then I looked up Ingrid's age and even she was 11 years younger than Grant! She's 43 here and Grant is 58. He truly did get better with age.
