Rogue One is a Star Wars movie unlike any other Star Wars movie. There’s no John Williams fanfare or opening crawl. Yes, Darth Vader makes an appearance, and the Death Star looms large over the plot, but the majority of characters — along with key locations and vehicles — are previously unknown to the galaxy far, far away. With that in mind, we have put together a quick primer to get you up to speed on the new film, which arrives in theaters on Friday. Think of it as our version of one of those classic war room briefing sessions from the “Skywalker saga” films. There are no spoilers here. All the information is culled from previously released Star Wars movies and TV shows, the recently released book Catalyst: A Rogue One Novel, as well as interviews with the Rogue One cast and filmmakers, trailers and TV spots, and publicity information.
