The new trailer expands further on the central storyline: Jyn Erso (Felicity Jones) is recruited by the Rebel Alliance when they learn that the Empire has been working on a powerful new space station for twenty years. They discover that Erso's father, Galen (Mads Mikkelsen), is the designer of the station's energy weapon and may know of a weakness. Erso forms an elite infiltration and retrieval squad consisting of blind spiritual warrior Chirrut Imwe (Donnie Yen), expert pilot Bodhi Rook (Riz Ahmed), heavy weapons expert Baze Malbus (Jiang Wen), former Onderon rebel leader Saw Gerrera (Forest Whitaker), reprogrammed Imperial assassin droid K-2SO (Alan Tudyk) amd Rebel handler Cassian Andor (Diego Luna). Their mission is to sneak into the construction site of the space station and retrieve its plans. Needless to say, things soon go wrong and Imperial Director Orson Krennic (Ben Mendelsohn) is soon on their trail for his boss, an apparently mostly off-screen Darth Vader (James Earl Jones).
The trailer gives us some pretty cool new visuals, including our first proper look at Hannibal's Mads Mikkelsen as Galen Erso and our first (very brief) glimpse of Y-wings and AT-STs in the movie.
Galen Erso and his daughter Jyn, when she is a young girl. From their ages and the plot of the tie-in novel Catalyst: A Rogue One Story, this scene takes place about 20-23 years before the events of Rogue One, during the closing stages of the Clone Wars.
An Imperial-clas Star Destroyer hanging out over the planet Jedha.
Galen Erso at an Imperial facility, where he is presumably working on the Death Star's superlaser weapon.
Director Krennic looking villainous.
The Death Star orbiting the planet Scarif, where it is in the final stages of completion.
Bodhi Rook comes up with the "Rogue One" designation for the infiltration squad.
TIE fighters doing a flyby of the Death Star.
The Rebels learn about the Death Star and collectively freak out.
AT-STs are deployed to help detain the Rogue One squad.
Dudes hanging out, possibly on Jedha.
Chirrut Imwe schooling some stormtroopers with his marksmanship (he's blind but can apparently sense the location of living beings through a unique Force connection, although he's not a Jedi and does not use a lightsabre).
Rebel Alliance X-wings attack an Imperial space station above Scarif. I suspect this is during the extraction of the Rogue One team, after the Death Star has departed.
This X-wing pilot looks vexed.
X-wings continue the attack, taking out laser turrets on the station. The Rebel fleet has hyperspaced in behind them, with both Rebel Transports and Nebulon-B frigates visible. There might be a Mon Calamari Star Cruiser in the fleet and there's certainly Mon Calamari in the Rebel base, which will get timeline fans arguing about things (the assumption being that the Mon Calamari didn't join the Rebellion until after The Empire Strikes Back, given the lack of Star Cruisers in the fleet in that film).
Stormtroopers getting blown up. Must be Friday.
The planet Jedha has a very bad day.
Darth Vader turns up for a quiet word with Director Krennic.
Rebel U-wings attempt to extract the Rogue One team from Scarif. The big walkers aren't actually AT-ATs but cargo walkers adapted for defence. It's possible that this film gives the Empire the idea of converting them into dedicated war machines.
Cassian Andor, Jyn Erso and K-2SO sneak into an Imperial base, presumably on Scarif.
The all-important title card.
Star Wars: Rogue One (or Rogue One: A Star Wars Story) will be released worldwide on 16 December.
