For the first twenty years of motion picture history most silent films were short--only a few minutes in length. At first a novelty, and then increasingly an art form and literary form, silent films reached greater complexity and length in the early 1910's. The films on the list above represent the greatest achievements of the silent era, which ended--after years of experimentation--in 1929 when a means of recording sound that would be synchronous with the recorded image was discovered. Few silent films were made in the 1930s, with the exception of Charlie Chaplin, whose character of the Tramp perfected expressive physical moves in many short films in the 1910's and 1920s. When the silent era ended, Chaplin refused to go along with sound; instead, he maintained the melodramatic Tramp as his mainstay in City Lights (1931) and Modern Times (1936). The trademarks of Chaplin's Tramp were his ill-fitting suit, floppy over-sized shoes and a bowler hat, and his ever-present cane. A memorable image is Chaplin's Tramp shuffling off, penguin-like, into the sunset and spinning his cane whimsically as he exits. He represented the "little guy," the underdog , someone who used wit and whimsy to defeat his adversaries .
Eisenstein's contribution to the development of cinema rested primarily in his theory of editing, or montage, which focused on the collision of opposites in order to create a new entity. One of the greatest achievements in editing is the Odessa Steps sequence, in his film Potemkin (1925). Eisenstein intercut between shots of townspeople trapped on the steps by Czarist troops, and shots of the troops firing down upon the crowd. Members of the crowd became individual characters to viewers as the montage continued. Within the editing track the fate of these individuals was played out. A mother picks up her dead child and confronts the troops. Then she is shot. A student looks on in terror and then flees--his fate uncertain. An old woman prays to be spared, but she is killed by a soldier who slashes her face with his saber. When a woman holding her baby carriage is killed, she falls to the steps, and the carriage begins a precipitous decline--shots of the baby crying are intercut with wide shots of the carriage rolling down the steps. To Eisenstein, each individual shot contributed an energy within the editing track that yielded far more than the sum total of shots. In other words, the "combination" of shots through editing created a new entity, based on the expressive emotional energy unleashed through the editing process .
