There are some things everyone seems to know about Alfred Hitchcock. One of these is how brilliant he was, the other is that he is the master of suspense and the third is his egoism. As someone exceptionally influential and charismatic, it was natrual for him to pose in front of the camera of the most famous photographers. Maybe this is the reason why many of the pictures of him are outstanding and beautifully artistic.
