Most of the movies made before sound hit the big screen will never be seen by our eyes. According to Martin Scoresese's Film Foundation, half of the films made pre-1950—and more than 90 percent of those made before 1929—are lost forever. And while not all of them are lost, you'll probably never see the films that remain, since they're rarely screened. Their posters remain as last relics of Hollywood's beginnings.
