A silent movie is a movie made without sound. Silent movies were made from the late 1880s to the early 1930s. They used early cameras that could not record sound. The reasons why were either because the movie was being made before sound cameras were invented or because the movie makers could not afford sound cameras. Charlie Chaplin was known as one of the best movie stars during "The Silent Era", as it's called today in movie history. Other popular movies include Nosferatu: A Symphony of Terror, A Trip to the Moon, The General, and Metropolis.
