The term "prequel" has also been applied to origin-story reboots, such as "Rise of the Planet of the Apes", "Batman Begins", and "Casino Royale". The creators of both "Batman Begins" and "Rise of the Planet of the Apes" also stated their intent to dispense with the continuity of the previous films so they would exist as separate pieces of work, with Christopher Nolan—director of "Batman Begins"—explicitly stating he does not consider it a prequel. Here, "prequel" denotes status as a "franchise-renewing original" that depicts events earlier in the (internally inconsistent) narrative cycle than those of a previous installment. Most reviewers require that a prequel must lead up to the beginning of its original work, which is inconsistent with works that dispense with the narrative of previous work and are not significantly within the same continuity. At times, the term has been used to refer to a work that was released, as well as chronologically set, before any other work. However, that usage conflicts with the fact that a prequel is a type of sequel.
