Parts of one of Alfred Hitchcock’s earliest films, 1923’s The White Shadow, have been discovered by the New Zealand Film Archive, according to the Associated Press. It is the only known copy of the silent film, which Hitchcock wrote, edited, and served as assistant director and art director. The film’s first three reels (three others remain missing or destroyed) were donated to the Archive in 1993 after the death of a projectionist who had collected old silent films. The Academy of Motion Picture Arts and Sciences in Beverly Hills will host a special screening of the film on Sept. 22.
