The post-'Game of Thrones' box-office sweepstakes officially kicked off this past weekend with... a resounding thud. After the success of the HBO fantasy drama based on the George R.R. Martin book series, it's not too surprising that the ensemble cast might set their sights on box-office glory. First up! Jason Momoa -- who played the ferocious Khal Drago in 'Thrones' -- attempted to reboot the long-dormant 'Conan the Barbarian' franchise. And, well, as pointed out here, 'Conan' now owns the 23rd worst opening of all time (when opening in over 3000 screens). So! What do the other residents of Westeros have planed?
