'Rogue One: A Star Wars Story' behind the scenes trailer and poster released

LONDON, July 15 (UPI) -- As part of the Star Wars Celebration event in London, fans were treated to some special behind-the-scenes footage of the upcoming film Rogue One: A Star Wars Story, which premieres in December.

The footage that everyone wants to see – basically anything with Darth Vader – wasn't released online, but a special behind-the-scenes look crafted specifically for the Celebration event was posted to the official Star Wars Twitter, along with a poster featuring Rebel forces battling Stormtroopers on a beach while the Death Star looms in distant space.

The video features interviews with cast and crew of the upcoming film, with most of the buzz being generated by Warwick Davis, whose role in the film is not yet known.

Rogue One: A Star Wars Story opens on Dec. 16 and will be followed by four more confirmed films through 2020.
