Production has been under way since August on Rogue One: A Star Wars Story, the first Star Wars spinoff that will hit theaters next December. Gareth Edwards signed on to direct last year, with Gary Whitta (After Earth) writing the first draft of the screenplay, before Chris Weitz (Cinderella) took over the writing duties in January. Today we have a new report from Latino-Review, which claims that Mission: Impossible Rogue Nation writer-director Christopher McQuarrie came aboard at some point to provide a script polish.

The filmmaker reportedly did a "two-week pass" on the script, but it isn't known how much he changed from Chris Weitz's draft, or when exactly Christopher McQuarrie performed this polish. The filmmaker had a shortened post-production schedule on Mission: Impossible Rogue Nation, when Paramount pushed it from a Christmas Day release to July 31. It's possible that he started work on the script just after wrapping up his promotional tour for Mission: Impossible Rogue Nation, giving him just enough time to complete a polish before filming on Rogue One: A Star Wars Story began in mid-August.

All we know about the Rogue One story is that it follows a group of Rebels who hatch a mission to steal the original Death Star plans. The cast includes Felicity Jones, Mads Mikkelsen, Ben Mendelsohn (who is reportedly playing the villain), Alan Tudyk, Diego Luna, Forest Whitaker, Donnie Yen, Riz Ahmed, Jonathan Aris and Wen Jiang. It isn't known how much principal photography is left on Rogue One: A Star Wars Story, or when we may see the first trailer.

Christopher McQuarrie won an Oscar for his original screenplay The Usual Suspects. His other writing credits include The Way of the Gun, his directorial debut, along with Valkyrie, The Tourist, Jack the Giant Slayer and Edge of Tomorrow. He also wrote and directed Jack Reacher and Mission: Impossible Rogue Nation.

It has been rumored that Rogue One will be the first Star Wars movie to be shot in 70MM. Director Gareth Edwards is reportedly using the Ultra Panavision 70 anamorphic lenses which were created specifically for Quentin Tarantino's The Hateful Eight. That has never been confirmed, but we'll have to wait and see as more information starts coming in for Rogue One. What do you think about Christopher McQuarrie possibly polishing the script for Rogue One: A Star Wars Story?
