Shhh!

Americans require a restful quiet in the moving picture theater, and for them talking from the lips of the figures on the screen destroys the illusion. Devices for projecting the film actor’s speech can be perfected, but the idea is not practical. The stage is the place for the spoken word. The reactions of the American public up to now indicate the movies will not supersede it.

— Thomas Edison, quoted in the New York Times, May 21, 1926
