Production got under way last month on Disney and LucasFilm's first Star Wars spinoff Rogue One: A Star Wars Story, which takes place between Star Wars: Episode III - Revenge of the Sith and Star Wars: Episode IV - A New Hope. We've already seen the first set photos, which reveal a few actors playing Stormtroopers. Today, TMZ uncovered more photos that show some sort of massive spaceship crash, along with several dead Stormtroopers floating in shallow water. What could this all mean? We don't have a single clue, but we can spot a few of the main cast members in these images, including Felicity Jones.

The story will center on a group of Rebel Alliance soldiers who go on a mission to steal the Empire's plans for the original Death Star. Felicity Jones leads the cast that also includes Riz Ahmed, Sam Claflin, Diego Luna, Ben Mendelsohn and Forest Whitaker. It isn't known how long production is expected to last, but LucasFilm and Disney have already announced a December 18, 2016 release date. The movie currently doesn't have any other movies opening against it at the box office next December.

There have also been several unconfirmed rumors that have been swirling around the set, most of which involve the identities of main characters. Felicity Jones, for instance, is rumored to be Boba Fett's daughter, while Diego Luna is rumored to be Biggs Darklighter. Mads Mikkelsen's signature on a fan's poster are leading some to believe he could be playing Galen Marek, a character from the Star Wars: The Force Unleashed video game. It seems unlikely that we'll get confirmation on any of these characters' identities anytime soon, but we'll have to wait and see.
