A comedy of errors is a narrative work that is light and often humorous or satirical in tone, in which the action usually features a series of comic instances of mistaken identity or other misunderstanding, and which typically culminates in a happy resolution of the thematic conflict. Wikipedia

A theater play, movie, or the like, where mix-ups of persons or concepts, mistaken assumption, planned or accidental misunderstandings, betrayal, and confusion play a central role in the plot. Usually, the audience has most or all background knowledge, while acting characters remain confied to a limited individual sight. Both fun and excitement or thrill stem from these conflicting sights.
