Alfred Hitchcock is known worldwide as one of the greatest directors of all time. His iconic shots in films such as Psycho, North by Northwest, Strangers on a Train, Birds, and others, all contribute to this stellar reputation. He was a pioneer in the film industry, creating many firsts. He was the first to have cameo appearances in his own films, and due to his immense talent for creating suspense in all of his films, became known as "The Master of Suspense." He originated the idea of suspense due to non-disclosed information, rather than sheer horror, a technique utilized in many films by many other directors in later times.
