Two of the biggest bad guys in the star wars franchise are returning for the anticipated star wars spinoff Star Wars: Rogue One. According to Darth Vader will return and have a big presence in the spinoff, but he will be joined by the devious Sith Lord who is expected to be working behind the scenes, and will be seen on display screens and holograms throughout the flick. It is unclear if we will see the main protagonist come across these two villains. The film is set to take place during the height of the Empire’s power and it follows a group of Rebel soldiers who unite to take on a dangerous mission to steal the plans for the Death Star. The current cast consists of Oscar nominee Felicity Jones as the lead hero, Diego Luna, Ben Mendelsohn, Riz Ahmed, and Oscar winner Forest Whitaker. The first teaser trailer for the film was shown at the Star Wars Celebration back in April, and it’s been said to be darker and more grounded than its predecessors.

Filming is said to have already begun and the film hits theaters December 16th, 2016.
