Everything we know about the next 'Star Wars' movie 'Rogue One'

We're just months away from the premiere of "Rogue One: A Star Wars Story," and Disney has released the first official teaser trailer for the standalone film.

Taking place before the events of the 1977 original film, "Rogue One" follows Jyn Erso (Felicity Jones) and a group of Rebel fighters on a mission to steal plans for the Death Star.
