Sometimes "prequel" describes followups where it is not always possible to apply a label defined solely in terms of intertextuality. In the case of "The Godfather Part II", the narrative combines elements of a prequel with those of a more generalized sequel by having two intercut narrative strands, one continuing from the first film (the mafia family story under the leadership of Michael Corleone), and one, completely separate, detailing events that precede it (the story of his father Vito Corleone in his youth). In this sense the film can be regarded as both a "prequel and a sequel" (i.e., both a prior and a continuing story), and is often referred to in this manner.
