I conceived that scene in terms of the participants’ desire not to interrupt the romantic moment. It was essential not to break up the mood, the dramatic atmosphere. Had they broken apart, all the emotion would have been dissipated. And, of course, they had to be in action; they had to go over to the phone that was ringing and keep on embracing throughout the whole call, and I also felt that the public, represented by the camera, was the third party to this embrace. The public was being given the great privilege of embracing Cary Grant and Ingrid Bergman together. It was a kind of temporary ménage à trois. – Alfred Hitchcock
