Game of Thrones star Jason Momoa has apologised after footage emerged of him joking that one of the perks of the show is that he gets to "rape beautiful women".
American actor made the comments at a 2011 Comic-Con panel discussion, drawing laughter from the crowd but not from co-star Lena Headey.
Momoa, who plays Khal Drogo on the long-running HBO fantasy show, said filming rape scenes was an enjoyable aspect of working on the series.
"But as far as sci-fi and fantasy, I love that genre because there are so many things you can do, like rip someone's tongue out of their throat and get away with it and rape beautiful women," he said.
Following outrage over the remarks, the star took to Instagram to apologise.
"I am still severely disappointed in myself at the insensitivity of my remarks that day," he said.
"I know my sincerest apology now won't take away those hurtful words.
"Rape and sexual harassment can reach anyone and I have seen first hand its painful torment among members of my own family and friends."
Momoa has been filming the Aquaman movie in Queensland with co-stars Amber Heard and Nicole Kidman.
He also plays Aquaman in the film Justice League, set to be released next month.
In his post, Momoa said he awoke in Australia to the "justified" reactions to the "distasteful joke".
He called the comment "truly tasteless."
"It is unacceptable and I sincerely apologise with a heavy heart for the words I said," he said.
Momoa's Justice League co-star Ben Affleck
has also come under fire this week over footage that emerged of him groping an MTV host during a 2003 interview.
Affleck yesterday apologised for groping co-host Hilarie Burton's breast live on air during MTV's music video show Total Request Live.
Just days earlier, he had said he was "saddened and angry" to hear about sexual abuse allegations against Hollywood heavyweight Harvey Weinstein.
Revelations about Weinstein's alleged sexual harassment of dozens of women including Rose McGowan, Ashley Judd, Gwyneth Paltrow and Angelina Jolie have put a spotlight on the issue of sexual harassment in the entertainment industry.
