Darth Vader, the greatest bad guy of all time, has been long confirmed to appear in Rogue One: A Star War Story this December. Over the weekend in London, Disney unveiled a new trailer for Rogue One: A Star Wars Story at Star Wars Celebration in Europe. The new solo Star Wars movie takes place prior to the events of Star Wars: Episode IV but after those of Star Wars: Episode III. The film will be filling in some of the blanks on Vader's rise into the powerful villain fans all know and love. The new trailer has a very brief shot of Darth Vader standing over a display panel on the Death Star.
