Jason Momoa can't wait for fans to hear what Khal Drogo will say next,  especially following last week's shocking Game of Thrones conclusion, in  which he gave his brother-in-law Viserys a "golden crown" of molten  death.
In last Sunday's episode, "You Win or You Die" (airing  9/8c on HBO), an enraged Drogo delivers a lengthy speech after his wife  Daenerys (Emilia Clarke) is threatened. It not only reveals his martial  side, but also shows that the previously quiet leader of the nomadic  Dothraki can string together more than a couple words.
"I'm  dying for my friends to see me make the speech," Momoa tells  TVGuide.com. "My friends who watch the show all just keep saying, 'Dude,  you don't say anything. You're just naked!' And I'm like, 'I swear to  God, I say stuff!' Drogo makes this beautiful war speech and dedicates  it to his wife. He's going to f--- some s--- up."
Up until now, 
the khal has been taking more of the  imposing, silent partner role in the marriage -- having wordless sex in a  tent and occasionally grunting while sitting next to the campfire. 
"I  base him off of a silverback or a lion," Momoa says. "It was my first  time ever to play a king kind of role. You wanted to make him  stone-faced, sort of impenetrable. Being arrogant was fun, you know? But  when I go back home after work, my wife would slap me back down. She's  like, 'You have to take the garbage out.'"
Although Khal  Drogo isn't relegated to garbage duty in his marriage, Daenerys does  have an influence on him. 
"He's a super-stoic character but when he  falls in love with this beauty, you slowly start to find his  heartstrings," Momoa says. "He warms up to someone, which is something  he's never done before. Drogo is starting to open up."
Although  playing such a role and dealing with its rigorous language requirements  were new to Momoa, physically at least, he seemed born to play Drogo. 
In  fact, he had just finished shooting Conan the Barbarian, the remake of  the classic Arnold Schwarzenegger film in which Momoa plays the titular  warrior. When he went on to shoot Game of Thrones in Belfast, Ireland,  he found the muscle mass acquired to play Conan helpful to embody Drogo.
		
		
	
	
"It  was great coming off of Conan because it was really hard training,"  says the actor. "For Conan I had to eat boiled chicken breast and work  out all the time and basically eat like a bird every two hours and stay  ripped. But I'm bigger in Game of Thrones. Drogo is like 7-feet tall in  the book. So after training really hard for five months, when I got to  Ireland, I had Guinness, pizza, spaghetti and whatever I wanted. You put  all that fat on top of the muscle and you look heavyweight. I gained so  much weight. Later, we had to go back for a photo shoot and I was 30  pounds lighter. I didn't even fit into my wardrobe, the minimal wardrobe  that I had."
Even though Drogo doesn't wear much clothing, 
the  actor found that the hair and makeup helped him get into character.  Among the Dothraki, the length of one's braid indicates their success in  battle. Drogo remains undefeated, which is why he's the khal.  Another touch added to the character -- that wasn't described in George  R.R. Martin's A Song of Ice and Fire novels on which Game of Thrones is  based -- is his heavy eyeliner.
"It was interesting to find a  wig that wasn't too heavy but was long enough," Momoa reveals. "They  clipped it on in the back and wove it in. The eyeliner thing came about  just because in doing the research, you learn the nomads travel across  plains and deserts. They always wear the eyeliner so it reflects the  sun. That's why I designed it for that. I thought it would be a good  character trait."
Luckily, the actor didn't have to contend  with any makeup malfunctions, namely runny eyeliner.
Quite the  opposite in fact. "No, it didn't run," he says. "I had so much on I  guess it completely caked everywhere."
In fact, Momoa found he  had difficulty removing the eyeliner at the end of the night, which  created some difficulties when walking around Belfast.
"The  show wanted me to keep my own mustache so I had this horrible '70s porn  mustache on," he says. "So I was walking around Belfast -- I'm  dark-skinned and 6-foot-5, with eyeliner and a really disgusting  mustache -- and I'd have to apologize to people and say, 'Listen, I'm  sorry. I'm working here. No, not as a transvestite, but I'm working on a  show.'"
Game of Thrones airs Sundays at 9/8c on HBO.
