With Rogue One: A Star Wars Story hitting theaters this year, it's interesting to know that we still know very little about this movie and the characters, despite it being named the Most Anticipated Movie of 2016 by Fandango. We do have Felicity Jones' character possibly revealed, but other than that? Nilch.
That will obviously change in the coming months, but there's also the possibility we'll see the first trailer in May when it's attached to Marvel's Captain America: Civil War.
According to MakingStarWars.net, Rogue One's first trailer could be with Civil War, as both are Disney properties now. Disney could release the trailer a week before the movie, much like with The Force Awakens, but we'll have to see how things end up in the coming weeks.
Rogue One is the first of the new standalone live-action movies that will sit outside of the "Episode" or "Saga" films. The plan for Disney/Lucasfilm is to have a Saga film - one of the ones with "Episode #" in front of it - every other year, with "A Star Wars Story" movie in the years between Rogue One tells the story of the elite unit of the Rebel Alliance on a mission to steal the plans to the Empire's new mega-weapon, the Death Star. It takes place shortly before the original Star Wars, now also known as Star Wars - Episode IV: A New Hope, and shortly after the events of the animated series Star Wars Rebels.
Rogue One: A Star Wars Story is directed by Gareth Edwards, and scheduled for a December 16, 2016 debut. See where it and other Star Wars films sit on our full franchise movie release schedule.
