Rogue One: A Star Wars Story is available on Digital HD and coming to Blu-ray this week. Set before the events of Star Wars Episode IV: A New Hope, the movie focused on the mission first described in the opening crawl of that movie. A small group or Rebels faced incredible odds in order to seek out the Death Star plans.
As the first stand-alone film in the franchise, the movie broke away from the traditional format. The main characters were new, and there was no connection to the Skywalkers–except for Darth Vader’s small role.
