The film was shot in eight weeks, and required no retakes. During the scene where James Stewart hiccups when drunk, you can see Cary Grant looking down and grinning. Since the hiccup wasn’t scripted, Grant was on the verge of breaking out laughing and had to compose himself quickly. Stewart thought of hiccuping in the drunk scene himself, without telling Grant. When he began hiccuping, Grant turned to Stewart saying, “Excuse me.” The scene required only one take. [x]
Los Angeles, 4 april 1947 - Katharine Hepburn, James Stewart and Cary Grant perform ‘The Philadelphia Story’ for a radio broadcast. Cary Grant did not like the idea of seeing Katharine Hepburn in slacks and so he donned a skirt during rehearsals of the radio broadcast. Miss Hepburn was burnt up about something else, namely the manner in which the bobby-soxers pulled their swoon act every time Cary appeared. In protest against them she is removing her bobby sox right in the studio.
