 The film was shot in eight weeks, and required no retakes. During  the scene where James Stewart (I) (qv) hiccups when drunk, you can  see Cary Grant (qv) looking down and grinning. Since the hiccup  wasnt scripted, Grant was on the verge of breaking out laughing and  had to compose himself quickly. James Stewart (I) (qv) thought of  hiccuping in the drunk scene himself, without telling  Cary Grant (qv). When he began hiccuping, Grant turned to Stewart  saying, "Excuse me." The scene required only one take.
