The Tramp in Keystone director Mack Sennett's company of players. Chaplin continued to play the Tramp through dozens of short films and, later, feature-length productions. (In only a handful of other productions did he play characters other than the Tramp). The Tramp was closely identified with the silent era, and was considered an international character. When the sound era began in the late 1920s, Chaplin refused to make a talkie featuring the character, partly due to how the character was supposed to be American, and Chaplin himself had a strong and obvious British accent. The 1931 production "City Lights" featured no dialogue.
