After attending the premiere of the film, Cole Porter supposedly remarked to his wife, Linda, "if I could survive that, I can survive anything."
When the studio asked Cole Porter whom he might like to play him in the movie, Porter suggested Cary Grant as a joke. He thought Grant was about as far from himself as you could get. The studio went and signed Grant to play the role.
When a friend of Cole Porter's heard that Cary Grant had been cast to play the songwriter in the film of his life, the friend asked Porter why he had not objected since he and Grant looked nothing alike. The friend pointed out that Porter might have suggested Fred Astaire instead, another good friend of his who had a strong physical resemblance to him. Porter replied, "If they wanted Cary Grant to play you in a movie, would you complain?"
