With a total revenue of over three billion dollars, the Twilight saga box office numbers are truly impressive. Based on Stephanie Meyer's series of fantasy romance novels, the Twilight saga consisted of five movies released annually between 2008 and 2012. Despite generally mixed-to-negative reviews from critics, each movie in the Twilight saga did outstandingly well with audiences and helped launch several similar Young Adult novel adaptations. Although many of the films made in its mold at the time failed commercially, Twilight itself remains an excellent example of the subgenre's capability for financial success.
