An intermission is a break in the middle of a film, normally in a feature-length film of three hours or more (although rare in current-day films). Originally, intermissions served as a "stretch-restroom" opportunity, or provided time for the projectionist to change reels. They often were accompanied by a medley of the film's score or a song score for musicals. The strategy of film theaters nowadays is to show a film as many times as possible during the day.
