A double act is a form of comedy originating in the British music hall tradition, and American vaudeville, in which two comedians perform together as a single act, often highlighting differences in their characters' personalities. Pairings are typically long-term, in some cases for the artists' entire careers. Double acts perform on the stage, television and film.
