The official trailer for “Rogue One: A Star Wars Story” has since dropped, featuring new footage from what we have seen thus far in the various teasers et al, along with further dialog (“Can we remove your shackles?” - wow!), and the presence of the Sith Lord himself, Darth Vader! (Or at least the back of his helmet hahahaha).
The film would have to try really hard to disappoint though … but then again, the hype for The Force Awakens by far superseded the result of the film itself tho, IMHO. But I choose to remain “optimistic” :)
"Rogue One: A Star Wars Story in which a group of unlikely heroes band together on a mission to steal the plans to the Death Star, the Empire’s ultimate weapon of destruction." (Premieres December 16, 2016 / More screenshots HERE on Facebook)
