Auteur Theory

French film critics, most notably by Francois Truffaut, articulated auteur theory in the 1950s. The concept describes the mark of a film director in terms of thematic or stylistic consistencies, personal aesthetic vision, recurring themes, established technique, a defined view of the world and a significant degree of control over production. He suggested that this meant that the director should therefore be regarded as an auteur.

How can Hitchcock be regarded as an auteur? What was his style?

Alfred Hitchcock excelled in a variety of genres during his early British career, before moving to Hollywood in 1939. It was here he became known as the 'Master of Suspense', producing some of the most analyzed works in the history of cinema.  Hitchcock often made cameo appearances in his films, representations of the psychological and elongated suspense scenes.

The auteur theory now applies to music videos.
