James Stewart and Cary Grant on working together in George Cukor's "The Philadelphia Story" (1940) & how this memorable scene was improvised: "James Stewart: I play a writer who falls in love with Katharine Hepburn. The night before her wedding I have a little too much to drink. This gives me the courage to go and talk to Cary, who’s playing her ex-husband. So I go to Cary’s house and knock on the door. It’s obvious I’ve had too much to drink, but he lets me in. It was time to do the scene, and Cary said, ‘George, why don’t we just go ahead? If you don’t like it, we’ll do it again.’ So, without a rehearsal or anything, we started the scene. As I was talking, it hit me that I’d had too much to drink. So, as I explained things to Cary, I hiccuped. In answer to the hiccup, Cary said —out of the clear blue sky —‘Excuse me.’ Well, I sort of said, ‘Umm?’ It was very difficult for me to keep a straight face, because his ad-libbed response had been so beautifully done. Cary had an almost perfect humor. Cary Grant: Jimmy simply mesmerized me on the screen. When I watched him act, I felt like a triangle player in the orchestra who keeps watching the conductor and then, when he finally gets the baton signal, he misses his triangle."
