That locks down a long touted rumour that the iconic villain will indeed be part of the Imperial effort to keep the plans for the first Death Star out of rebel hands and that he will be acting as the Emperor's enforcer. Which will be a subject of concern and fear for Ben Mendelsohn's (Killing Them Softly) Director Krennic. Who will actually play Vader in the suit has yet to be announced, but you can bet James Earl Jones has been in the sound booth recording that memorable rumbling voice.
Gareth Edwards (Godzilla) has been shooting – and more recently reshooting – the film, which includes some impressive looking Imperial hardware, and we are promised more details of exactly what red Felicity Jones' Jyn Erso has in her ledger, which she is looking to get wiped out by helping the Rebellion.
Rogue One: A Star Wars Story will be out on 16 December.
