You can now stream Alfred Hitchcock's "The White Shadow" (1924), the earliest surviving feature by the director. As I posted in 2011, the "lost" movie turned up in a New Zealand film vault. The film stars Betty Compson as twins, one angelic and one evil. Unfortunately, only half of the film's six reels were found, making it a true cliffhanger.
