Comedy films aim to provoke laughter and entertainment through lighthearted and humorous stories with happy endings. They exaggerate situations, language, actions, and characters for comic effect. Comedies observe human flaws and frustrations, providing temporary relief from everyday life. Some common subgenres include romantic comedy, parody, and gross-out comedy. In the 1930s, the arrival of sound films led visual slapstick to decline, but verbal and dialogue-driven comedy rose in popularity, exemplified by stars like the Marx Brothers, Laurel and Hardy, and Jack Benny.
