Star Wars Anthology: Rogue One has added yet another cast member with Diego Luna signing on for the highly-anticipated spinoff. Actor Ben Mendelsohn, who has long been rumored to to star, has now been confirmed to play the primary villain. They join a cast that already includes Felicity Jones, Riz Ahmed and Sam Claflin.

The story revolves around a group of rebel fighters who embark on a mission to steal plans for the original Death Star. The story will take place between the events of Star Wars: Episode III - Revenge of the Sith and Star Wars: Episode IV - A New Hope, but closer chronologically to the latter film. Felicity Jones, Riz Ahmed and Diego Luna are all said to be playing rebel fighters, but it isn't known who Sam Claflin is playing quite yet.
