Star Wars: New Rogue One trailer released

Felicity Jones plays rebel fighter Jyn Erso in Rogue One: A Star Wars Story

A new trailer for Star Wars spin-off Rogue One has been released, offering fans a fleeting glimpse of Darth Vader.

The trailer concludes with a shot of Vader and the sound of his trademark heavy breathing.

Felicity Jones stars in Gareth Edwards' film as the leader of a Rebel mission to steal the plans for the Death Star.

The film is set before the time of the first Star Wars film A New Hope, released in 1977, and does not form part of the main series.

The two-minute promo, which is different from the one shown at last month's Star Wars Celebration event in London, begins with new character Saw Gerrera (Forest Whitaker) telling Jyn Erso (Jones) that "the world is coming undone".

"Imperial flags reign across the galaxy," his voice continues over a shot of an Empire vessel floating above a desert landscape.

Mexican actor Diego Luna also forms part of the film's international cast

The trailer goes on to show Jyn and Cassian Andor (Diego Luna) being told about the mission for which they have been selected.

Subsequent scenes feature a new robot character voiced by Alan Tudyk, a blind warrior played by Hong Kong action star Donnie Yen, and an Imperial Walker being struck by a missile.

Actress Alyssa Milano, screenwriter Max Landis and DJ Edith Bowman are among those to welcome the new promo on Twitter.

US publication Entertainment Weekly, meanwhile, has assembled a frame-by-frame analysis.

Rogue One: A Star Wars Story will be released in the UK on 16 December.
