A lost 1920s Alfred Hitchcock film that provides clues into the legendary director's early working style has been discovered in New Zealand, archivists said on Wednesday. Recently uncovered film "The White Shadow" features a 24 year-old Hitchcock's work as a writer, assistant director, art director and editor. The film was first released in 1924. It is considered to be the earliest surviving feature film in which Hitchcock received a credit, according to the U.S.-based National Film Preservation Foundation. Only the first three of the movie's six reels survive. That adds to the movie's mystery, which some film buffs see as fitting for Hitchcock, because he was famous for creating mysterious stories full of suspense.
