Along with Princess Leia, this Reddit list also named a few other classic Star Wars characters who could appear in Rogue One.
Assuming this list is correct, then Rogue One will feel like a good old fashioned homecoming week more than it already does.
Guy Henry is listed as playing Governor Tarkin, a character who has long been rumored to appear in the spinoff and who was integral to the creation of the Death Star.
Anthony Daniels is also supposedly reprising everyone’s favorite golden protocol droid, C-3PO (R2-D2 was not mentioned), while Game of Thrones actor Ian McElhinney is listed as playing General Dodonna, the man who walked the Rebel pilots through the strategy to destroy the Death Star in A New Hope.
