Alfred Hitchcock

Alfred Hitchcock directed a number of films, some of his most famous ones are:

He was famous for films that often had an unusual, or distinctive look to them (though, that's really from when he moved over to America, and much of the look of a movie is due to the director of photography and the editor, rather than just the director), usually with some twisted plots, superb cinematography, and a pervading musical score by Bernard Herrmann.
