Ranking second behind Grint and Watson is reported real-life couple Kristen Stewart and Robert Pattinson, the stars of the Twilight franchise. All of the Twilight films to date have hit theaters in the last five years, earning $2.5 billion at the global box office. While the Harry Potter series is mostly about Potter’s journey, the Twilight franchise is centered on Stewart and Pattinson’s characters, the human Bella and the vampire Edward. In the most recent movie they got married, with disastrous results. They’ll have a chance to boost their earnings even more when the second part of the last book, Breaking Dawn, is released this coming November.
