Final Rogue One trailer gives fans more deets

Los Angeles - The final trailer for the hotly-anticipated Rogue One: A Star Wars Story dropped Thursday, giving fans more insight into the beginnings of the saga's rebel alliance two months ahead of the movie's release.

The first standalone Star Wars story, Rogue One is set just before A New Hope - the original film in the blockbuster series - and stars Felicity Jones as rebel Jyn Erso alongside Mads Mikkelsen and Forest Whitaker.

Following a grand Star Wars tradition, the trailer teases a film preoccupied with the themes of family loyalty and the conflicts of parenthood - with the usual weird aliens, light sabers and stormtroopers thrown in for good measure.

The first full-length trailer released in August gave fans their first glimpse of Darth Vader since 2005's Revenge of the Sith.

Viewers are again treated to a split second cameo by the Dark Lord of the Sith, this time from the front as he listens to the Empire's Director Orson Krennic (Ben Mendelsohn) boasting about the awesome power of his new toy.

It has not been revealed which actor has been hired for Vader's latest big screen outing, due to hit theatres on 16 December.
