Rogue One: Star Wars prequel characters revealed as Darth Vader appearance teased

Ben Mendelsohn is - as predicted - on the dark side

Ben Mendelsohn's Rogue One character has been revealed

Now the Force Awakens haze has ascended, all eyes are on the next Star Wars property to be released - prequel Rogue One.

A trailer surfaced last month providing a glimpse of many actors confirmed to be in the film - Felicity Jones, Diego Luna, Ben Mendelsohn - but, save for Jones' rebel protagonist Jyn Erso, the brief clip gave no details on any of the film's characters.

However, JediBibliothek has somehow unearthed the film's visual guide (we should note that it's a work in progress) which has thrown forth some exciting information surrounding these characters and their allegiances.

Moreover, it all but confirms the appearance of legendary villain Darth Vader; more on that below.

First, the characters. In the good camp, we have:

Felicity Jones as Jyn Erso, a gifted soldier and warrior.

Diego Luna as Captain Cassian Andor, an officer in the Rebel Alliance

Jiang Wen as Baze, a freelance assassin

Alan Tudyk as the CGI figure K-250, a Vollstreckerdroide and evidently an imperial model, but teams up with the rebels.

Riz Ahmed as Bodhi, a rebel soldier.

Donnie Yen as Chirrut, a spiritual warrior.

Pao and Bistan who are two aliens described as being "fierce warriors".

Then, perhaps unsurprisingly, in the not-so-good camp, there is Mendelsohn whose character Krennic is the military director of the Empire. His job is to defend the Galactic Empire against the theft of Mission rebels (who plan to destroy the Death Star in events preceding A New Hope).

It's the picture shown as part of the visual guide's mock-up that's most exciting, however; a double page spread showing the rebel alliance and the Empire, Darth Vader is tantalisingly placed in the centre of the page.

While it's been heavily hinted that he'll be showing up in the film - and, considering the timeline, it'd be odd if he wasn't there - this is currently the firmest evidence yet pointing towards an appearance for old Vader.

You have full permission to get insanely excited. Rogue One - A Star Wars Story will be released 16 December 2016.
