I was reading rumour mill crap all yesterday evening.
Of course none of that stuff is confirmed and a great deal of it is just attention seekers who make plausible-sounding claims using known information. Plus god knows how much of it is actual staff-driven misinformation. Seems like it would be more absurd to imagine someone producing a Star Wars movie without a comprehensive misinformation campaign.
But the one thing that is unquestionably known and which has me thinking is the cast. It's just so damn big! I mean, there are nearly twenty people with major speaking roles and significant screen time in this movie. All storyline rumours aside I'm really wondering how bloated the movie might wind up being.
