Some of his fellow stars, including Lena Headey and Emilia Clarke, can be seen looking awkward, covering their faces or hanging their heads after his comment.
Watch it below:
Momoa expanded on his comments in a follow-up interview with the New York Post.
"Yeah, I'm raping Emillia (Clarke). I love her, but I'm hurting her and she's crying. We could have made it longer, but you get the idea. I'm not a rapist. I prefer my women to enjoy sex."
He also told Celebitchy: "...I'm not a rapist. It really did not feel good. There was no enjoyment. I don't like women crying when I'm making love to them."
The video has been shared widely on social media since Weinstein's downfall, with one user calling it "horrific".
Others defended the clip, saying it was old and it was referring to his character in the show.
Momoa is set to star as Aquaman in DC's upcoming Justice League film, as well as a stand-alone Aquaman film.
Justice League also stars Ben Affleck, who apologised yesterday over a groping incident during a TV interview in 2003 with Hilarie Burton.
