As I said on the other thread, this is only a rumour so far with information gathered from a so called 'reliable' source. Nothing has been confirmed yet and Momoa denied that he was Aquaman a while back. Nonetheless, if it were true, I could see Momoa pulling this role off. There are some similarities in Karl Drogo's role that can easily be applied to Aquaman plus he's a pretty good actor to boot with the physicality to match Aquaman's appearance. This could potentially work well if true.
