Earlier this year, the trailer for Star Wars: Rogue One was unveiled to thunderous applause.
The film was Star Wars, but not quite as we know it. There was the Death Star and AT-ATs, but not a Force user in sight, and the general tone was darker and grittier.
Since then, we've had more information, with character names, vehicles, and part of Mads Mikkelsen's character revealed (but still not seen). Most recently, reports have started surfacing of reshoots. If they're to be believed, Disney want to bring the tone closer to the original trilogy, and also shoehorn in a cameo from young Han Solo Alden Ehrenreich.
There may be truth in some of that, but then reshoots are nothing out of the ordinary, and given the success of The Force Awakens I'm inclined to trust them with this. The idea of reshoots, though, does reinforce the idea of how little we still know about this film, despite the latest reveals.
Although the bones of the plot were worked out 40 years ago, Rogue One remains a film shrouded in secrecy. We don't know much about who these characters are, where they're from, or how they wind up invovled in a plot to steal the Death Star plans.
It means a lot of questions have been thrown up, and in the absence of any potential answers, it's no surprise that there are lots of theories - though some of them are more believable than others.
