Star Wars fans went into a tizzy today, as the teaser trailer for Rogue One: A Star Wars Story officially made its debut. The film is a special one since it's set several years before 1977's Star Wars: Episode IV A New Hope.

The plot follows Felicity Jones (who scored a leading role as a rebel fighter), who is given an operation to steal the Empire's plans for the Death Star.

Also starring in the film are Riz Ahmed, Diego Luna, Ben Mendelsohn, Mads Mikkelsen, Jiang Wen, Forest Whitaker, Donnie Yen and Alan Tudyk (he will play a motion-capture character). And here's a fun fact: Rogue One is the first Star Wars movie without any Jedi.

Look out for Rogue One: A Star Wars Story (directed by the Godzilla remake's Gareth Edwards) when it hits theaters Dec. 16 of this year. But don't be confused! Episode VIII, the follow-up to The Force Awakenswill arrive December 2017. Get into the teaser above, and click here for a roundup of ridiculous Star Wars music mashups.
