A comedy film is a film genre that emphasizes humor. These films are designed to amuse audiences and make them laugh. Films in this genre typically have a happy ending, with dark comedy being an exception to this rule. Comedy is one of the oldest genres in film, and it is derived from classical comedy in theatre. Some of the earliest silent films were slapstick comedies, which often relied on visual depictions, such as sight gags and pratfalls, so they could be enjoyed without requiring sound. To provide drama and excitement to silent movies, live music was played in sync with the action on the screen, on pianos, organs, and other instruments. When sound films became more prevalent during the 1920s, comedy films grew in popularity, as laughter could result from both burlesque situations but also from humorous dialogue.
