If you're on the fence about this series, one view of the latest trailer might just change your mind. Actually, it definitely will.
At the beginning of the trailer, we see a massive Star Destroyer hovering a little too close to the ground of an unnamed forest planet, signifying that the Empire is about to start making its first moves. On top of that, we're also brought to the familiar Galactic Senate Chamber on Coruscant, which—so far—is the only confirmed (and recognizable) planet we've seen.
We see Cassian Andor (Diego Luna) dressed up and posing as a member of the Empire, likely in an effort to hack into their system and extract some sort of rare piece of intelligence. Luthen Rael (Stellan Skarsgård) is shown speaking to Andor, telling him that, "The Empire is choking us so slowly, we're starting not to notice. What I'm asking you is this: wouldn't you rather give it all to something real?"
It seems like Rael is one of the main masterminds behind the budding Rebellion movement, and because of his involvement, it's mentioned in the trailer that pockets of rebels are beginning to pop up in various places across the galaxy. In addition to Rael, we also get a glimpse into our old friend, Mon Mothma's (Genevieve O'Reilly,) beginnings. Though we all know her as being one of the founders of the Rebel Alliance from Return of the Jedi, we never got a chance to see her origin story, which she teases in the trailer by saying, "As long as everyone thinks I'm an irritation, there's a good chance they'll miss what I'm really doing."
And if that's not enough, we get a very quick look at an alien who looks a lot like Maz Kanata from The Force Awakens. Someone get me a matching pair of goggles.
