Darth Vader is back in the new trailer for the latest film in the Star Wars franchise Rogue One.
The teaser also reveals some of the movie's plot as we see the main character - played by Felicity Jones - being told by her father in a flashback that everything he does is to protect her.
But she's later told that her dad is critical to the development of the Death Star.
The film will be released in December.
