AKA: FranchiseA sequence of films with continuing characters or themes, but with little other interdependence, especially with respect to plot or significant character development. Until the advent of television series, there were various film series such as The Thin Man and Blondie that were started with the intention of making more than one. In subsequent years, the term would apply to features such as Star Trek: The Motion Picture or Dr. No that made more than one sequel. In modern times, the term franchise has been used (perhaps cynically) to describe to the practice of creating a movie and product-marketing package which is contingent on commercial success. Batman and its sequels are typically used as an example of a franchise. Contrast with serial.
