Sound revolutionized film, plain and simple. It shifted mass gears in the large industrial complex that comprised movie-making, putting many silent stars out of jobs, and forcing filmmakers to find a entirely new talent pool to choose from. Sound design is a vital element to many films, allowing filmmakers to suggest and explore worlds, creatures, and ideas off screen as well as on. In a medium such as cinema, how could sound be anything but a colossal reinvention of the craft?
A vintage documentary on the birth of sound in the movies has been unearthed by Les Introuvables En Cinéma, starting with a great opening talk from legend Walter Cronkite before diving into his narration of the history of sound. Using clear, laymanized terms, the documentary gives a slightly hokey but informative look into film projection, the creation and utilization of sound in movies, and the endless possibilities this created.
