His apology comes after footage showing Momoa joking about his character and the "rape attractive women" while speaking at a Comic-Con panel resurfaced online.
The Game of Thrones star, who plays Khal Drogo in the series, commented on the things that he's able to get away with in the science fiction and fantasy genres.
Footage has emerged of Game of Thrones star Jason Momoa joking that one of the perks of the show is that he gets to "rape lovely women". Perhaps he sees that in even more stark relief in light of the accusations his Justice League costar Ben Affleck is facing.
"I love that genre, there's so many things you can do, like rip someone's tongue out of their throat and get away with it and rape handsome women", Momoa said.
"Tonight i saw a disgusting clip of jason momoa making a rape joke and i am absolutely repulsed".
The video has been shared widely on social media since Weinstein's downfall, with one user calling it "horrific". We could have made it longer, but you get the idea. In a Facebook post, the father of three said he is "saddened and angry" that an influential personality would use his power to manipulate women for sexual gain.
Momoa will next appear as Aquaman in the upcoming Justice League film.
