Last we saw Jason Momoa, he was landing in San Francisco Bay along with the entire crew of Atlantis in the finale of Stargate Atlantis. The good news for fans of the strapping Hawaiian-born actor is that he will appear soon in HBO's upcoming Game of Thrones pilot, based on George R.R. Martin's fantasy book series A Song of Ice and Fire.
Momoa is reportedly being cast as Drogo, according to the Winter Is Coming blog. Momoa supposedly announced the casting at Armageddon Expo in Melbourne, Australia:
He just got the call the other day, and he said it hadn't been announced. He'll be filming in Morocco and doesn't like horses, so isn't looking forward to the horseback scenes. He also said that it'll be his first nude scene and first sex scene. ...
He also said when he went in for the audition he did a haka, as he thought it would be perfect for Drogo.
(A haka is a traditional Maori dance, so we've just learned.)
Here's how Wikipedia describes Momoa's character:
Drogo is a powerful khal, or warlord, of the Dothraki people, a tribal nation of expert riders and raiders in the steppes beyond the Free Cities. He is an accomplished warrior and has never been defeated in battle.
We're just spit-balling here, but it sounds like a good fit for the man who was Ronon.
The large ensemble cast also includes Nikolaj Coster-Waldau, Sean Bean, Mark Addy, Kit Harrington, Jennifer Ehle, Jack Gleeson, Peter Dinklage and Harry Lloyd.
