The "Justice League" star, who played the role of Khal Drogo during season one and two, also put to rest the rumours about his return on the show. "Just knowing how amazing this season is going to be... It's going to be the greatest thing that's ever aired on TV. It's going to be unbelievable," Momoa told Entertainment Weekly.
"It's going to f**k up a lot of people. And it was a bummer because I'm a huge fan and I didn't want to know what's going on. I was like, 'Damn, I didn't want to know that!" he added.
The actor recently paid the cast a visit while in Belfast which led to fans speculating that his character is returning to the show.
"I just showed up to see (producers David Benioff and Dan Weiss) and I just happened to see people on set," Momoa said.
"I haven't been over there in a long time. You just want to see your friends and you end up make headlines going, 'Drogo's back!' and I'm like, 'He's dead! He can't come back, it wouldn't work.'" he added.
