He is one of the most influential and widely studied filmmakers in the history of cinema. Known as the "Master of Suspense", he directed over 50 feature films in a career spanning six decades, becoming as well known as any of his actors thanks to his many interviews, his cameo roles in most of his films, and his hosting and producing the television anthology Alfred Hitchcock Presents (1955–65).
