For those of you who have made it this far, this story — as directed by Godzilla helmer Gareth Edwards — follows the rebels who manage to steal the plans to the Death Star that eventually lead into the events of Star Wars: Episode IV — A New Hope.
But it’s place on the Star Wars timeline explains why this dude is able to show face.
So it’s a prequel, but also a sequel to Revenge of the Sith.
The footage expands on a lot of what we saw in the previous Rogue One trailers, giving more meat to the scenes and backfilling more information on Jyn Erso, her past, and her recruitment into the Rebellion by Mon Mothma.
