As a photographer you are an intruder, which Henri Cartier-Bresson had already realized. "One must approach one's object, even it is only a still life, with the utmost care, on velvet paws, but Argus-eyed", was his advice. "Anything, but no pushing and shoving - who wants to fish, must not ruffle the water." The forays are of course more easily accomplished, if you are dealing with professionals who like to be caught. With Alfred Hitchcock, for example, I only had to walk through Hamburg and ask him, "Mr. Hitchcock, please play Mr. Hitchcock for a little while." Everything else he did himself. He precisely knew the look of the camera, he played and flirted with it like a woman who feels the eyes of an admirer on her. On a launch in the port he conspiratorially peered out of a cabin door, in the old Elbtunnel he posed as a killer in the stairwell. It was a magnificent 20 minute silent movie, directed and played by Alfred Hitchcock. When a journalist once walked into the picture, Hitchcock barked at him in the jargon of the studios: "Get out of the picture!"
