In the movie Suspicious Carry Grant tickles Joan Fontaine under her chin to try to get her to smile while his friend makes funny faces at the same time. This goes on for like 10 seconds and he attempts it twice but unfortunately she's upset and we don't see her smile. The camera angle was behind her though so she might have been smiling and laughing in real life lol. Anyway I just thought this scene was worth mentioning because Carry Grant was doing the tickling. First Irene Dunne and Ginger Rogers and now Joan Fontaine? I wonder how many other beautiful actresses he's tickled lol, going to have to watch more of his movies and not just because he's a great actor lol.
