Game Of Thrones star Richard Dormer has hit out at "annoying" leaks about the TV show and suggested some could be done on purpose.
Last year, season seven's episode four and its script appeared online before it was officially broadcast.
Four people were arrested in India in August 2017 following the leak and police said the suspects had company credentials that gave them access to episodes in advance.
Also, episode six was accidentally leaked online last year by HBO Spain, reports said.
It was then pulled within an hour, but that was still long enough for it to reach the wider internet.
The eighth and final series of the hit show is due to air on HBO and Sky Atlantic from April 2019 and Dormer, appearing on Sky News, refused to reveal any details about it, joking "they would kill me".
The actor, who plays Beric Dondarrion in the fantasy drama, said it was annoying that leaks surfaced on the internet as "we want fans to see it on screen and go, 'Oh my God, I can't believe it'".
"You don't want it to be spoiled. You want it to be a piece of entertainment, constantly keeping you on the edge of your seat."
But he said the leaks were "good for the show".
He told Sky News: "It gets people talking. Sometimes I suppose they even leak stuff on purpose. I don't know but it's all good for the show."
Dormer, from Lisburn in Northern Ireland, was speaking ahead of the start of the third and final season of Sky Atlantic's Scandinavian thriller Fortitude, in which he plays police officer Dan Anderssen.
He said he was going to miss the role, calling Anderssen a "brilliant character".
Dormer said: "He's very funny. very scary, very dark. A lot of fun."
He also praise the sense of humour in the show, adding: "It kind of makes sense to me".
The show was filmed in Norway where, according to Dormer, the temperature got as low as -55C (-67F)

"As long as you are wearing the right clothes and have a nice big furry hat you will be absolute fine," he added.
:: Fortitude starts tonight on Sky Atlantic at 9pm.
