As you can see, the poster features the film's entire principal cast, in addition to Darth Vader who sneakily appears over the Death Star in the top right corner over Jyn Erso's shoulder. The classic Star Wars villain is set to appear in the film -- marking the first appearance of the character in live-action since Disney bought Lucasfilm several years ago.

Directed by Gareth Edwards (“Godzilla,” “Monsters”) from a script by Gary Whitta and Chris Weitz, “Rogue One” stars Felicity Jones, Mads Mikkelsen, Alan Tudyk, Donnie Yen, Forest Whitaker, Diego Luna and Riz Ahmed.
