In the latest trailer for Rogue One: A Star Wars Story, viewers are given more information regarding Jyn Erso and her father Galen Erso (played by Mads Mikkelsen). The protagonist is appointed to lead a Rebel Militia force—they presumably are on a collective quest to find Erso’s father and reveal some sort of collusion that he had in the construction of the Death Star. All in all, the nearly three-minute clip is equally as dramatic as it is action-packed. Not to mention, viewers are treated to a brief appearance of Darth Vader. Watch the second and final official trailer above and expect Rogue One: A Star Wars Story to hit theaters on December 16.
