Anyone else think the Mountain looked like he's never held a sword in his life? Yes, they got the guy who looked the part, until the fight began.
Sort of hard for a guy to look skilled when he is being absolutely fucking clowned by the guy he is fighting.
Pretty much this. Oberyn was way faster than him and a much more skilled fighter. Probably most anyone would have looked like garbage in his shoes.
I thought he did fine. Anyone have a gif of Oberyn getting his teeth ktfo?
