“Rogue One” came to Star Wars Celebration in London and left the crowd dying for more. After kicking off with a poster reveal, which you can see below, “Rogue One: A Star Wars Story” director Gareth Edwards showed a new trailer — loaded with new footage and behind-the-scenes moments — to the crowd. That can be seen above.

There was one secret piece of footage, though. As the panel came to a close, a new trailer for “Rogue One” was shown. It introduced all of the key players and was filled with footage of the battle to come. The icing on the cake, however, was a reveal of Darth Vader (James Earl Jones) at the end, which sent the crowd into an uproar. Edwards spoke briefly about recording dialogue with Jones around Christmas being a true highlight of his life. Sadly, at least for now, this trailer is a Celebration exclusive. However, tons of juicy information about “Rogue One” was dropped in the panel.

The key to so much of “Rogue One” seems to be how much of the movie is done practically, rather than using green screens and CGI to fill the frame. Included in the trailer was footage shot in the Maldives, which subs in for a new planet in the “Star Wars” universe called Scarif.

As the post we shows, this planet — which Edwards referred to in the panel as a “paradise world” — will be the hone of a major battle between Imperial forces and the Rebellion. Interestingly, Edwards used the Maldivian army to play the roles of an army of Stormtroopers — though none of them knew what “Star Wars” was.

Meanwhile, the movie will largely focus on Jyn Erso (Felicity Jones) and her team as they attempt to steal the plans for the Death Star. One of her team members is a new droid, which is actually an Imperial droid that the Rebels have control of.

K2SO is voiced by Alan Tudyk and will serve as the closest confidant of Cassian Andor (Diego Luna), a Rebel Alliance officer. Additionally, Bodhi Rook (Riz Ahmed) is the team’s pilot and is questioning his allegiance as his home planet is occupied by the Empire.’’

After recently learning who Mads Mikkelson would be playing — Galen Erso, Jin’s father — the actor wasn’t too keep on spilling many more details, other than the fact that he’s a scientist and has the potential to alter the world.

Finally, Ben Mendelsohn took the stage to talk about his character, the villainous Krennic. “He is smarter, I think, than most of his predecessors,” Mendelsohn teases.

“Rogue One: A Star Wars Story” is in theaters Dec. 16.
