The first trailer for the Star Wars spin-off film ‘Rogue One’ has been released by Disney, and the first thing you’ll notice is the storm troopers’ change of uniform. Besides the new look, the sneak peak also reveals teasers about the lead female character, Jyn Erso.

Played by British actress Felicity Jones, Erso is described as “reckless, aggressive and undisciplined,” in short, everything that promises sparks will be flying off the silver screen come December when the much-awaited release is going to happen. Supporting Felicity Jones in the cast are Forest Whitaker, Riz Ahmed and former Bond-villain Mads Mikkelsen.

The film is directed by Gareth Edwards, who has titles such as ‘Godzilla’ and ‘Monsters’ to his credit. This will mark the first of a series of Star Warsthemed adventure that will move away from the core of the original film.

The plot of ‘Rogue One‘ focuses on a group of rebel fighters whose mission is to steal the plans for the Death Star. The action actually takes place before the events of the 1977 original ‘Star Wars’. It’ll be interesting to see whether the spin-off will have fans flocking to theaters as eagerly as they do for the real thing.
